Remove PoolDoc from the packing sleeve. Carefully inspect all items to ensure that no solutions have leaked or any visible damage has occurred.
If the items you received do not match the chart above, please immediately contact the store where you purchased the item or the Watts Customer Service Department at 1-800-752-5582.

IMPORTANT:

• Extra care should be taken when handling the test vials: surface scratches, finger smudges, stains or water on the outside of the test vial surface may cause measurement errors.
• Test vials have two lightly frosted sides. Handle by the frosted areas or by the cap and bottom only.

Hints and Tips for Best PoolDoc Readings

Collecting a Water Sample

• Immerse a clean uncapped plastic bottle, glass, or cup upside down 12 to 18 inches below the water surface.
• Invert it allowing it to fill with water and remove it from the pool or spa.

Test Vial Care and Information

1. Test vials have two clear sides and two lightly frosted sides. Handle vials only or the frosted areas. Do not touch the clear sides.
2. Test vials have an arrow on one of the clear sides. This arrow must be aligned with the arrow on the PoolDoc Test Well when testing.
3. Test vials and caps should be rinsed thoroughly at least 3 times with clean water after each use or test to prevent chemical carryover from test to test.
4. Wipe test vials with a very soft, absorbent cloth to avoid scratching.

Using the Syringe

• If properly cared for, the syringe will last a very long time. It should be used only to transfer pool or spa water to the test vials.
• It is the most convenient way to measure the correct amount of pool water; exactly 3ml. It may take some practice to use.
• Be certain to empty and dry the syringe after each use.
• Transferring a Water Sample to a Test Vial
• Fill a clean test vial with exactly 3 ml of pool water using the supplied syringe.

Note:

• Use exactly 3ml using the syringe. The fill line on the cuvette is not 3ml.
• Carefully wipe any water from the outside of the test vial.

Using the Dropper Bottles (liquid reagents)

• WARNING: Please read all safety instructions, product labels, and Material Safety Data Sheets (MSDS) before using reagents.
• Proper use of the dropper bottles (fig. 2.1) involves uncapping and inverting the dropper bottle over the test vial and squeezing gently.
• For proper drop size, it is important to hold the dropper bottle as vertically as possible.
• It is normal for dropper bottles to develop excess reagent around the nozzle. Simply use a paper towel to blot this excess reagent.

Note:

• Some reagents such as the pH and the A2 can stain hands and furniture.
• It is recommended to work over an old towel or newspaper to avoid damage.
• All reagents have a limited shelf life. Be sure you are using fresh chemicals and replace any that have passed their expiration date.
• The expiration dates are listed on the bottle and dispenser labels.

Dosing Test Chemicals

• Remove the bottle cap and clean the nozzle. Vertically align the bottle directly over the test vial and gently squeeze until the correct number of drops are introduced into the test vial water.
• Recap the bottle and return it to the storage case.

Using the Powder Pop Dispenser

• Fig. 2.2 shows a DPD Powder Dispenser. The Powder Dispenser provides convenient and accurate doses of DPD reagent for chlorine and bromine measurements.
• To use the dispenser, flip the protective cap out of the way, invert the dispenser, shake gently, place directly over the top of the test vial (as shown) then firmly depress the dispenser button once to deliver the reagent.
• The protective cap must be replaced after each use to keep the powder dry. Never let the dispenser or the powder inside get wet.

Mixing the Test Chemicals in the Test Vial

• After chemicals have been added to the test vial water, recap the test vial and place your fingers at the top and bottom of the vial.
• Gently invert at least three times (DO NOT SHAKE). Air bubbles can cause errors but can usually be removed by slowly inverting the vial.

Note:

The DPD powder may not dissolve completely. This is normal.

Getting Started With PoolDoc

• IMPORTANT! BEFORE USING YOUR POOLDOC YOU MUST READ THIS SECTION CAREFULLY AND FOLLOW ALL DIRECTIONS.
• IF YOU FAIL TO DO SO, YOU WILL NOT BE ABLE TO GET THE CORRECT RECOMMENDATIONS FOR THE CONTROL OF YOUR POOL/SPA.

Battery

• PoolDoc is shipped without the battery installed. On the underside of PoolDoc, remove the two screws retaining the battery cover with the provided screwdriver.
• The battery fits under the cover (fig. 3.1). The polarity is printed on the battery compartment.
• Match the polarity of the battery compartment with the polarity of the battery. Replace the cover and tighten the screws for a watertight seal.
• Dropping or jarring PoolDoc during use may cause the battery contacts to bend slightly resulting in a loss of firm contact with the battery.
• If the instrument fails to turn on after being dropped or jarred, open the battery compartment and ensure there is adequate contact between the metal contacts and the battery.
• PoolDoc is a precision instrument that will give an accurate Rx “prescription” based on local desired levels and individual characteristics of your pool/spa.
• The size of your pool in Gallons/Liters, the specific types and concentrations of chemicals that will be used to adjust your pool/spa’s water balance, and the desired levels for your local areas must be entered into PoolDoc for it to provide an accurate Rx prescription”. Complete the table on page 7 of this manual under the column “My Pool”.
• If unsure of the information/settings, the professionals at your pool supply store should be able to help you.
• PoolDoc “Factory Settings” have been preset but some or perhaps all settings will have to be changed using the pool/spa water data that you have collected in this table.
• This data will remain in PoolDoc even in the event of battery failure or replacement. Only after your PoolDoc has “learned” your pool size and all other entries are completed accurately, are you ready to test!

NOTE:

• The concentration of the chemicals that are being used in PoolDoc must match the manufacturer’s concentration.
• Check the chemical’s packaging to determine the specific concentrations as this may vary among manufacturers.
• If you are unsure of these settings, your pool professional can assist you with the completion of the chart.

PoolDoc Set-Up Table

• PoolDoc has factory settings that show common DESIRED LEVELS for a pool’s chemical balance and commonly used maintenance CHEMICALS and their CONCENTRATIONS.
• You will need to confirm that the factory settings are correct or change them to those that are recommended by pool professionals in your area for your pool/spa.
• The pool/spa size, chemicals, ranges, and concentrations, taken from the data in the above table will provide PoolDoc with the correct references that enable it to give you accurate measurements and recommendations.

Settings that may need to be changed are:

• A. POOL SIZE B. USE OF A CHLORINATOR C. DESIRED LEVELS D. CHEMICALS USED AND CONCENTRATIONS.
• WARNING: Failure to properly set up PoolDoc and follow instructions may result in improper chemical balance, personal injury, and /or property damage.

Easy-To-Follow Data Entry Examples

• Several step-by-step illustrated examples follow that will quickly familiarize you with PoolDoc’s easy set-up.
• You will notice that PoolDoc’s screen shows prompts to assist you in many areas.
• Putting your data in PoolDoc is easy. Here’s how.

Entering Your Pool Size Data

• The very first time you turn PoolDoc on, a PLEASE READ screen will be displayed alerting you to go through the setup to allow PoolDoc to base its recommendations on your pool size, desired levels, and chemicals (fig. 3.2).
• Press MENU and the MENU screen will appear with the POOL INFORMATION line highlighted (fig. 3.3). Press ENTER.
• The POOL INFO screen will appear with the Pool Size line highlighted and show the factory setting of 0 gallons. To set PoolDoc to use metric units (Liters) scroll down to highlight the Metric Units line.
• Press ENTER to highlight the word NO, and press the UP ARROW ( ) to change the word to YES, and then press ENTER. You must then press MENU and then press ENTER to commit the change.
• Please refer to the Pool Size Calculator on page 23 to assist in determining the size of your pool in Gallons (or Liters).
• Press ENTER to highlight the number of Gallons/Liters (fig. 3.4). Use the PLUS (+) button until the number of Gallons/Liters of your pool/spa is reached.
• Press ENTER to add that number to PoolDoc memory. Your pool/spa size is now set into PoolDoc memory.
• Press the DOWN ARROW ( ) to highlight the Chlorinator line and press
• ENTER. Use the UP ARROW ( ) or DOWN ARROW ( ) to indicate if you are (YES) or are not (NO) using an automatic chlorinator.
• Press ENTER fig. 3.4 to enter your selection into PoolDoc memory.

Note:

• If you are setting PoolDoc up for a spa, set the Chlorinator to YES (fig. 3.5).
• PoolDoc assumes you are using an automatic chemical feeder with spas and will not give a recommendation with the Chlorinator set to NO. Press MENU to return to the MENU screen.
• The maximum pool size that can be entered into PoolDoc is 100,000 fig. 3.5 Gallons/Liters. For larger pools, the Rx “prescription” will need to be calculated. Set PoolDoc for 100,000 Gallons/Liters and perform your tests normally.
• Divide your pool size (in Gallons/Liters) by 100,000 and then multiply the RX “prescription” by the result.
• For example, if the RX “prescription” is to add .5 (½) gallon muriatic acid and your pool size is 250,000 gallons, the resulting calculation would be 250,000 ÷ 100,000 = 2.5 then 2.5 X .5 = 1.25 gal muriatic acid.

Adjusting Pool CHEMICALS and CONCENTRATIONS

• As an example, let’s look at TOTAL ALKALINITY. It is very important to program PoolDoc with the chemicals and concentrations you are using. PoolDoc has “Factory Defaults” that are easily adjusted.
• You will need to enter your pool size in gallons and the chemicals and concentrations you are using before PoolDoc will give a proper Rx “prescription” based on your pool or spa.
• If any of the “Factory Defaults” correspond to the chemicals and concentrations that you are already using, just skip to the next setting without making changes. It’s easy. Here’s how.
• Press MENU and the MENU screen will be displayed with the POOL INFORMATION line highlighted. Press the DOWN ARROW ( ) to highlight the CHEMICALS line and press ENTER (fig 3.6).
• The CHEMICALS screen will appear with the TOTAL ALK CHEMICALS highlighted.
• Press ENTER and the screen will appear with the UP: BAKING SODA line highlighted (fig. 3.7). Press ENTER and BAKING SODA will be highlighted (fig. 3.8).
• Use the UP ( ) or DOWN ARROW ( ) to scroll to the chemical you are using to increase your TOTAL
• ALKALINITY LEVEL. When the chemical you are using is highlighted, press ENTER to place that chemical into PoolDoc memory.
• If you need to change the CONCENTRATION shown, push the DOWN ARROW ( ) to highlight the CONCENTRATION line. Press ENTER to highlight the % (percentage) (fig. 3.9). Use the PLUS (+) or MINUS ARROW (-) until the desired concentration % is reached. Press ENTER to place the new percentage into PoolDoc memory.
• To complete the TOTAL ALKALINITY data, you now need to tell PoolDoc which CHEMICAL is being used to LOWER the Alkalinity level in your pool.
• Press the DOWN ARROW ( ) to highlight the DOWN: DRY ACID line (fig. 3.10). Press ENTER to highlight the chemical shown (dry acid).
• Use the UP ( ) or DOWN ARROW ( ) to scroll until the chemical you are using is highlighted. When the chemical you are using is displayed, press ENTER to store that chemical in PoolDoc memory.
• If you need to change the CONCENTRATION % (percentage) of the chemical just entered, press the DOWN ARROW ( ) to highlight the CONCENTRATION % line.
• Press ENTER. The % value will be highlighted (fig. 3.11). Use the PLUS (+) and MINUS (-) buttons to enter the new % (percentage) and when the proper % is displayed press ENTER to place the new value into PoolDoc memory.
• Press EXIT to return to the CHEMICALS screen.
• You have now entered the Chemicals you are using and their concentrations for TOTAL ALKALINITY to increase (UP) or lower (DOWN) the Total Alkalinity level of your pool or spa.
• At the CHEMICALS screen, you can now follow the same easy procedures to highlight, select, and modify the Factory Preset values for FREE CHLORINE, pH, and BROMINE as may be necessary.

Note:

• The pool size, desired levels, use of a chlorinator, chemicals, and their concentrations can be entered or changed at any time including during testing or when viewing an Rx “prescription”.
• If a change is necessary at any time, press the MENU button to enter the new information into PoolDoc memory and PoolDoc will recalculate the Rx “prescription” based on the new settings.

• Because bromine is rarely dosed directly into spas, a mechanical brominator is commonly used. To raise or lower bromine levels follow the manufacturer’s instructions.
• For PoolDoc to give an Rx “prescription”, the use of a Chlorinator must be set to Yes in the POOL INFO screen

Adjusting DESIRED LEVELS

• Press MENU and the MENU screen will be displayed with the POOL INFORMATION line highlighted (fig. 3.12). Use the DOWN ARROW ( ) button to scroll to DESIRED LEVELS.
• With the DESIRED LEVELS line highlighted in the MENU screen press ENTER. The DESIRED LEVELS screen will now appear (fig. 3.13) with the TOTAL ALK (Alkalinity) line highlighted.
• Press ENTER. The TOTAL ALK LEVEL screen will appear (fig. 3.14). The Max (maximum) and Min (minimum) LEVELS will be shown with the Max level highlighted. To change the Max level number for TOTAL ALK press ENTER.
• The maximum level stored in  PoolDoc will be highlighted (fig. 3.15).
• Adjust that number using the PLUS (+) or MINUS (-) buttons until the desired number is displayed. Press ENTER to store that number in PoolDoc memory. If you are finished, press EXIT.
• If you need to change the Min LEVEL, use the DOWN ARROW ( ) button to highlight the Min level line and then press ENTER to highlight the value stored in PoolDoc. Adjust that number using the PLUS (+) or MINUS (-) buttons until the desired number is displayed. Press ENTER to store the desired number in PoolDoc memory.
• Once you are satisfied with the values, press EXIT to return to the DESIRED LEVELS screen. Follow the same simple procedures described above to adjust the DESIRED LEVELS of any setting (FREE CHLORINE, pH, or BROMINE) that requires new levels to accommodate your pool/spa requirements.

Taking a PoolDoc Reading (Example: Free Chlorine)

• Turn PoolDoc on and it will go to the TEST ZERO screen (fig. 4.1). Fill a test vial with exactly 3ml of fresh pool water using the supplied syringe and recap vial. Carefully dry any water on the outside of the vial.
• Align the test vial and PoolDoc arrows (fig. 4.2) and insert the vial into the PoolDoc well. Press Read. PoolDoc has now set any existing color in the test sample to “zero”. Use this sample for the next step.
• Using the down button highlight Free CL (fig. 4.3) and press Enter. PoolDoc will then prompt you on test sample preparation.
• Using the DPD dispenser supplied, add one dose of DPD powder by flipping the cap out of the way, gently shaking, inverting, and placing directly over the top of the cuvette as shown (fig. 4.4). Depress the button once to dispense, then recap the dispenser.
• Recap the vial and gently invert it at least three times. Pool water will change color if free chlorine is present. Dry any water on the test vial. If you notice air bubbles on the inside of the test vial, slowly invert to remove them.
• Align the test vial and PoolDoc well arrows and insert the vial into the PoolDoc test well. Press READ.
• If your Free Chlorine value is below 8.0 ppm*, PoolDoc will ask if you want to test for COMBINED CHLORINE (fig. 4.5). Press Yes to test for COMBINED CHLORINE or press No to go to the measurement screen (PoolDoc will briefly show the Free CL reading before going to the measurement screen). You can press Rx “prescription” at this point and PoolDoc will display a brief Rx “prescription” for chemical additions or press the UP ( ) or DOWN ARROW ( ) to go to the next test.
• If the Free Chlorine value is above 8.0 ppm, PoolDoc will not ask if you want to test COMBINED CHLORINE (see explanation on Page 15).

Note: For greatest accuracy, complete the entire testing session before pressing Rx “prescription” to obtain recommendations.
Congratulations!
You have completed your first PoolDoc reading.

Pool Water Tests

Taking a Zero Measurement

• PoolDoc uses color changes in the sample to perform its calculations. Zeroing the instrument eliminates any influences caused by color in the original pool water as well as fingerprints or debris on the test vials.
• There is no need to zero before each reading as long as you use the same test vial for each reading. Pooldoc will turn itself off automatically after 30 minutes of no use. If PoolDoc is turned off, it will request a new zero.
• To zero, simply fill a clean test vial with 3ml of pool or spa water, insert the test vial in the sample well, and then press the READ button. This water sample can be used for the next test only.
• A fresh 3ml water sample will be required for each additional test.

Total Alkalinity

• When total alkalinity is in the correct range, pH is buffered and generally will remain stable. Low Total Alkalinity can be harmful to pool surfaces causing deterioration and staining as well as damage to fittings.
• High Total Alkalinity can promote the buildup of scale and cause staining. In most instances, the total alkalinity should be adjusted before attempting to adjust any other chemicals.
• Measuring Total Alkalinity requires that two liquid reagents be added to a fresh pool water sample. Using the syringe, add exactly 3ml of pool water into a test vial. Add three drops of the A1 reagent.
• Cap and invert the sample at least 3 times. Do not shake. Then uncap and add three drops of the A2 reagent. Again, cap and invert the sample at least 3 times. Place the test vial into the sample well of the PoolDoc and press the READ button.

Free Chlorine

• Free Chlorine is sometimes called Available Chlorine because it is a measure of the chlorine that is available to disinfect the pool. Low chlorine levels can lead to the growth of algae and bacteria, which can cause a health risk and can make the pool look bad.
• High chlorine levels can lead to certain types of stains, irritation, and strong odors and increase the disinfection costs associated with your pool.
• To measure Free Chlorine, the DPD reagent will be added to a water sample with the DPD Powder Dispenser. Review section 2.0 on the proper use of the Powder Dispenser.
• Using the syringe, add 3ml of pool or spa water to a freshwater sample. Invert the Powder Dispenser and place it on top of the test vial. Press the button once to dispense the powder and recap the dispenser.
• Immediately cap and agitate the vial by inverting it 3 or 4 times. DO NOT SHAKE.

Note:

• Not all the reagent powder does not have to be fully dissolved. It is normal for some powder to remain in the bottom of the test vial.
• Rinse the test vial at least 3 times after use.
• Place the test vial into the PoolDoc sample well making sure to align the arrows on the test vial and the PoolDoc test vial well.
• Press the READ button. PoolDoc will read the sample, and then ask if you want to test for Combined Chlorine (if the Free Chlorine level is less than 8.0 ppm).
• Press NO to go to the next test or YES to continue to the Combined Chlorine screen. Do not discard this mixed solution after testing if you are going to measure the Combined Chlorine.

Note:

• PoolDoc will not ask if you want to test for Combined Chlorine if your Free Chlorine level is above 8.0 ppm. See the explanation under Combined Chlorine below.

Combined Chlorine

• The purpose of this test is to determine the Combined Chlorine Level, which is an indication of whether you should shock your pool.
• Using the water sample from the previous Free Chlorine Test, add two drops of the CL liquid reagent. Cap and agitate by inverting at least 3 times. Place the test vial into PoolDoc’s sample well and press the READ button.
• If your Combined Chlorine value is greater than 0.3 ppm, you should consider shocking your pool. Follow the instructions on your favorite pool shock. Rinse the test vial at least 3 times after testing.
• When your chlorine level is high (above 8.0 ppm), bleaching of the DPD reagent can occur which often results in inaccurate results. PoolDoc will not prompt you to do a Combined Chlorine test with a chlorine level above 8.0 ppm.
• To lower the chlorine level below 8.0 ppm either add the chemical you are using for Chlorine Down or let the level drop naturally through exposure to sunlight or other means.

pH

pH is a measure of the acidity of the water. There are three main reasons for measuring pH:

1. Economical use of chlorine. Chlorine is more effective between a pH of 7.0 and 8.0.
2. Comfort. A pH below 7.0 is too acidic for comfort.
3. Protecting pool surfaces and equipment. Keeping the pool water in the correct range prevents pool surfaces and equipment from premature deterioration.

To measure pH, start with 3 ml of fresh pool water in a test vial. Add two drops of the liquid pH reagent, Cap and agitate by inverting at least 3 times (do not shake).
Place the test vial into PoolDoc’s sample well and press READ.

Bromine

• If you are setting PoolDoc up for a spa, on the POOL INFO screen set the Chlorinator to YES (see page 8 under setting your pool size).
• PoolDoc assumes you will be using an automatic chemical feeder with spas and will not give an Rx “prescription” with the Chlorinator set to NO.
• Bromine is a common method of disinfection in spas. This measurement would be used in place of the chlorine measurements on page 13.
• Add 3ml of fresh spa water into a test vial. Invert the DPD Powder Dispenser and place it over the test vial.
• Press the button one time to dispense the reagent and recap the dispenser.
• Immediately cap the test vial and agitate by inverting it at least 3 times. DO NOT SHAKE. Place the test vial into the PoolDoc test well. Press READ.

Note:

• Not all the reagent powder does not have to be fully dissolved. It is normal for some powder to remain in the bottom of the test vial.
• Because bromine is rarely dosed directly into spas, a mechanical brominator is commonly used.
• To raise or lower bromine levels follow the manufacturer’s instructions.
• CAUTION: Dispose of all tested water down the drain. Do not dispose of test water in the pool/spa. Keep away from children or pets. Not for human consumption!

Rx “prescriptions

• One of the most important features that distinguishes PoolDoc from other pool and spa test kits is its ability to display an Rx “prescription” that will bring your pool or spa’s chemistry back into balance based on your pool or spa’s size, the chemicals you are using and their concentration as well as the desired levels for your area.
• Once you have finished all the tests you plan to perform, press the Rx button and PoolDoc will display a Rx “prescription” if needed to bring your pool’s chemistry back into balance.
• PoolDoc will take into consideration all the tested values and provide a prioritized Rx “prescription” based on all the tested values. As an example, if your Alkalinity is Low, Chlorine is High, and pH is High, PoolDoc will give an Rx “prescription” to adjust only the Alkalinity since Alkalinity affects the other readings and is the highest priority. After the Alkalinity has been “successfully adjusted”*, PoolDoc will give an Rx “prescription” to adjust the pH if necessary (after retesting) since it is the test with the next highest priority.
• After the pH is “successfully adjusted” (see page 17), PoolDoc will then give an Rx “prescription” to adjust the Chlorine if necessary (after retesting).
• PoolDoc will give all dry chemical RX “prescriptions” in cups (i.e. add 8 cups dry acid) or mL if using metric units.

To convert cups/mL to lbs/grams, use the following conversions:

• As an example: 4 cups of Baking Soda would equal 2 lbs. (4 cups X .50 lbs = 2.0 pounds)
• Successfully adjusted” means that the Rx “prescription” has been followed (chemical added, etc.), the proper time interval has passed before retesting (your pool water has had time to cycle through a full water turnover), and after retesting-the adjusted test is within the desired level.

Frequently Asked Questions (FAQ)

How can I tell when my reagents need to be replaced?

• On the back of the reagent kit is an expiration date for the kit and there is an expiration date listed on each of the reagent bottles. See page 17 to order a reagent replacement kit.

Why is testing of my pool/spa so important?

• Proper water balance is important, not only for the health and safety of the pool user but also for the pool/spa itself.
• Improper water balance can lead to skin discomfort, burning eyes, and the growth of bacteria and algae. It can also lead to corrosion of pool finishes, staining, damage to pool equipment, and higher maintenance costs.

What if my PoolDoc gets wet?

• The housing of the PoolDoc is water resistant but should not be immersed in water.
• If water gets into the PoolDoc optics (sample well), incorrect readings may result until the water is removed or dried.
• Use a paper towel to blot out as much water as possible and then allow the instrument to air dry.
• If the PoolDoc is accidentally dropped into the pool, it will float but should be removed and dried immediately.
• After drying the outside, remove the battery cover and battery and check for water.
• Blot out any water and allow it to air dry before turning it on.

Where is the best place to store my PoolDoc?

• The PoolDoc should be stored in its case in a climate-controlled area, preferably indoors.
• Sudden temperature changes can cause condensation inside the instrument and prolonged high temperatures may hurt the longevity of the reagents.

How often should I change the battery?

• The PoolDoc battery should last for the entire pool season. When the battery gets low, you will see a battery icon in the top right-hand corner.
• When the battery gets very low, the icon will start blinking. At this time readings may be inaccurate.

I have done a set of tests and the Rx shows a chemical I am not using, do I need to start over?

• No, you can go back and change the chemicals you are using, their concentrations, the desired levels, and pool size at any time and PoolDoc will recalculate its Rx “prescription” based on the new values without having to retest.

How do I clean the PoolDoc?

• The outside of the PoolDoc can be cleaned with a soft cloth and either water or a standard ammonia-free window cleaner.

Can I use other manufacturers’ reagents with my PoolDoc?

• No, other manufacturer’s reagents are not designed to the PoolDoc’s specifications and will not function the same as the original PoolDoc reagents.

If PoolDoc gives an Rx “prescription”, how long should I wait before retesting?

• The time interval before retesting will vary depending on the test being performed. 12 to 24 hours normally will give the pool time to react to the last adjustment.

Do I need to perform all the tests?

• While it is always best to perform all the tests, PoolDoc will test and give an Rx “prescription” for a single parameter.
• Certain recommendations can be dependent upon more than one test.
• To get the most accurate results, perform as many tests as possible.

How often should tests be performed?

• As a general rule, pools should be tested once per week. If you are making a chemical correction to your pool, you may want to retest after the normal time interval to ensure your pool’s chemistry is back in balance.
• Under normal conditions, PoolDoc comes with enough reagents to last one year.

Approximate Volume Calculations for Common Pool Shapes

Calculation units below (L, W, N, and AD) must be in Feet!

Rectangular Pools

• Determine the average depth by adding the depth at the deep end to the depth at the shallow end and dividing by two.
• The formula for calculating Rectangular Pool Volume in Gallons/Liters:
• Length x Width x Average Depth x 7.5 = Total Gallons (Feet)
• Length x Width x Average Depth X 1000 = Total Liters (Meters)

Free Form Pools

• Determine the average depth by adding the depth at the deep end to the depth at the shallow end and dividing by two.
• For the average width, add the narrowest point (N) to the widest point (W) and divide by two.
• The formula for calculating Free Form Pool Volume in Gallons/Liters:
• Average Width x Length x Average Depth x 5.9 = Total Gallons (Feet)
• Average Width x Length x Average Depth x 785 = Total Liters (Meters)

Oval Pools

• Determine the average depth by adding the depth at the deep end to the depth at the shallow end and dividing by two.
• The formula for calculating Oval Pool Volume in Gallons/Liters:
• Length (L) x Width (W) x Average Depth x 5.9 = Total Gallons (Feet)
• Length (L) x Width (W) x Average Depth x 785 = Total Liters (Meters)

Circular Pools

• Determine the average depth by adding the depth at the deep end to the depth at the shallow end and dividing by two.
• The formula for calculating Circular Pool Volume in Gallons/Liters:
• Diameter (D) x Diameter (D) x Average Depth x 5.9 = Total Gallons (Feet)
• Diameter (D) x Diameter (D) x Average Depth x 785 = Total Liters (Meters)
