THE MARINELAND ML-24BW(2)

This manual will provide you with the information you need to successfully operate and maintain your BIO-Wheel Live Seafood Display System. Please read it carefully and keep it for future reference. The Marineland ML-24BW(2) is an easy-to-maintain refrigerated system for displaying and holding large loads of live seafood under ideal water conditions. Its dual mechanical/chemical filtration and powerful commercial BIO-Wheel wet/dry biological filter ensure optimum water quality at all times. And the compact plumbing design allows for convenient self-contained installation. Your ML-24BW(2) system comes complete with everything you need to become fully operational:

Consumables:

Prefilter Pads (#CS1859)
Carbon Filtration Pack (#CS1826)
Biological Filter Material #2 (Dolomite: #C0402)
Instant Ocean® Lobster Salt (#CS0309)

Accessories:

Hydrometer (#CA1501)
Thermometer (#CA1502)
Lobster Rake (CA1503)

NOTE : To prepare for the possibility of extra water changes, we recommend the purchase of additional Instant Ocean Lobster Salt (enough for two water changes).

Special Features

Reverse Flow Filtration prevents compacting of filter bed, ensuring cleaner water and eliminating the need for periodic filter bed maintenance.
The thermostatically controlled Refrigeration Unit is capable of maintaining tank temperatures of 45°–70°F and can be preset to the exact temperature required by the system.
The UV Disinfection Unit helps stop the spread of bacteria and disease throughout the system. Water enters the UV Housing, where it is exposed to UV light. This exposure destroys the DNA of the organisms, preventing them from reproducing. After exposure, water exits and is returned to the system.
The Protein Skimmer employs heavy aeration to remove dissolved organic matter from the tank in the form
of foam. The foam is flushed from the system and deposited into a floor drain or waste receptacle.
Low Voltage Light Switch (located under the display unit) allows you to turn fluorescent display light off during non-business hours to reduce algae growth.
The Sump Level Indicator Light glows red if the water in the Sump drops below the desired level.

Inside the ML-24BW(2) System

In this closed system, prefiltered water exits the enclosed Sump beneath the BIO-Wheel Filtration Modules and from there flows to the Water Pump. From here water is pumped either through the Protein Skimmer, through the UltraViolet (UV) Disinfection Unit, or into the display tank via a spray bar or filter bed.
Water entering through the spray bars provides surface agitation while water passing up through the filter bed is pH-conditioned and chilled to proper temperature by the refrigeration coils.Water is drawn from the system through surface and bottom skimmers and is routed directly to the BIO-Wheel Filtration Modules.
As water passes through each module, mechanical and chemical filtration is provided by a polyfiber Prefilter Pad and Carbon Filter Pack. Filled with three lbs. of Black Diamond Premium Activated Carbon, the Pack adsorbs dissolved organic compounds that cause odor and discoloration.
After passing through the Filter Media Trays, filtered water spills onto the BIO-Wheels mounted below. Because system flow causes them to rotate, the BIO-Wheels are constantly exposed to both water and air, thus developing a thriving culture of aerobic nitrifying bacteria. This bioculture efficiently oxidizes all ammonia and nitrite on contact.
From the BIO-Wheels, prefiltered water re-enters the enclosed Sump for recirculation.

INSTALLATION

The following simple steps are required to get your system up and operational. Consult exploded views for any necessary clarification.

Tank Preparation

Locate the unit near a 110–120 volt grounded outlet with a 20 amp dedicated circuit.
WARNING : Do not attempt to operate the unit on an extension cord or non- grounded circuit. Do not handle or connect the plug with wet hands.
Make sure Vented Panels are not obstructed.(to avoid overheating, we recommend keeping an adequate distance between the vent and any barriers to ventilation.) These panels allow cooling air to reach the compressor. They provide access to filters, thermostats, on/off switches, drains, and other components.
Unpack all accessories, supplies, and upper false bottom from the tank.
Remove Vented Panels.Make sure system components are plugged into the Junction Box. NOTE: Cord receptacle outlets are labeled for clarity.If the cord becomes disconnected, be sure to reconnect to the designated outlet.
Attach the Foam Drain Tube to the drain outlet (shown) or skimmer cup.
NOTE : Because the Foam Drain Tube is designed to drain off excess liquids and foam from the Protein Skimmer, you will need to locate the tube over a bucket, container or floor drain.
Set the Thermostat at 50° F. See pg.17 for details.
Replace Vented Panels.

FILTRATION PREPARATION

IMPORTANT : Your system contains five types of filters:

Mechanical – Filter pads to screen out solid waste particles.
Chemical – Premium Activated Carbon to adsorb dissolved contaminants, discoloration, odors, and toxic gases.
Biological – BIO-Wheels and Dolomite to remove toxic ammonia and nitrites and help maintain pH balance.
Protein Skimmer to drive dissolved organic matter from water.
UV Disinfection Unit to eliminate waterborne bacteria, viruses, and algae spores.

NOTE : Ammonia (produced from animal waste and respiration) is the biggest killer of aquatic animals. For this reason, biological filtration is critical.
A biological filter is a living filter…aerobic beneficial bacteria that consume animal waste products and convert toxic ammonia to non-toxic nitrate. When properly maintained, it keeps your product alive and healthy, and your water clear. When a biological filter is overtaxed or abused, water clarity and product longevity will be affected. Use of precultured BIO-Wheels (optional) means no need for a lengthy (6-8 week) break-in period. Your bacteria culture is in place, ready to go to work. The product can be immediately loaded and displayed. We recommend that you make an effort to keep your lobster population relatively constant. Beneficial bacteria breathe oxygen but consume ammonia. No animals, no ammonia. No ammonia, no bacteria.

NEVER use soap or cleansers in or around the tank.
NEVER leave the tank turned off for long periods.
NEVER let a BIO-Wheel or gravel bed dry out.

Before system startup, follow the few easy steps outlined below to get your system ready for operation. Refer to the Exploded View (pg. 5) for additional clarification.
PLEASE NOTE: The BIO-Wheel Filtration Module for the ML-24BW(2) is located underneath the display tank in the Sump Chamber and accessible through the access panel (see Exploded View, pg. 5).

Remove the Sump Access Panel. Remove the Skimmer Cup and set aside.
Remove the top section of the Protein Skimmer by separating the Froth Cup from the Contact Chamber and disconnecting the Drain Hose from the Drain Port. Set aside.
Remove Prefilter Media Tray (slides out).
Remove the Carbon Filter Box.
Unwrap the Carbon Filter Pack and place in the Carbon Filter Box.
NOTE : Before installing, gently shake the cartridge to distribute carbon. Be sure to rinse the Carbon Filter Pack thoroughly in cold, clean water until the water runs clear.
Replace the Carbon Filter Box.
Place blue polyfiber Prefilter Pad inside Prefilter Tray.
Slide the Prefilter Media Tray into place above the Carbon Filter Box.
Replace the top section of the Protein Skimmer and reconnect the Drain Hose to the Drain Port with the Hose Clamp.
Replace the Skimmer Cup. Replace Vented Panels.

Filtration Bed

Remove Upper False Bottom (A). Pour one inch of Biological Filter Material #2 (Dolomite) onto Lower False Bottom (B) and spread evenly over the entire surface (C).
Open the Upper Tank Drain Valve (parallel to the Flow Tube – see arrow) and run water through the Dolomite (with the drain open) to flush out all the dust.
NOTE : To avoid spillage, position the System Drain over a floor drain. Close the Upper Tank Drain Valve when finished.
Place Upper False Bottom over layer of Dolomite.

SYSTEM STARTUP

For Saltwater Systems Only: Add approximately 28 lbs. of Instant Ocean Lobster Salt to tank. Save the remainder to adjust salinity at a later time.
NOTE : When filling tank, run water through salt to dissolve it faster.

Remove the Sump Access Panel. Fill the display tank until the water level in the Sump Indicator Tube is within Sump Maximum Water Level (on the side of the Sump). NEVER allow water level to go below indicated Sump Minimum Water Level (indicated).
Make sure the Upper Tank Valve (A) and Sump Drain Valve (not pictured) are closed (perpendicular to flow tube). Make sure the Return Valve (B) is open (parallel to the flow tube).
Start System. Plug power cord into the 110-120v dedicated outlet and turn the switch on. Never attempt to plug in the unit unless your hands and plug are absolutely dry.
Fill the remainder of the display tank with water until overflow into the Sump is initiated.

MEASURING SALINITY

After your system has been running for about two hours and water is clear, it is time to measure the tank’s salt level.

Remove the Hydrometer from the plastic tube.
Rinse the plastic tube and fill it with water from the tank.
Place the Hydrometer in the tube and tap the tube lightly so that the Hydrometer floats.
NOTE : You may also float the Hydrometer in the tank.
Read the scale on the tube. Reading should be between 1.020 and 1.025.If the reading is below 1.020, add salt; above 1.025, drain some water and replace with fresh water.1.022 is ideal.

When replacing water lost due to evaporation, simply add cold, clean tap water.
If water is removed for a specific purpose, e.g. to dip lobsters or clean tank, new salt and water will be needed.
Always wait for salt to dissolve before taking the Hydrometer reading.
Never pour new salt into tank if lobsters are present. Use a clean container to dissolve salt (approximately 1.5 lbs of salt to every 5 gallons of water).

INSTALLING BIO-WHEEL

BIO-Wheels are the newest innovation in live seafood holding system filtration. A BIO-Wheel is the ideal culture site for beneficial bacteria…bacteria that eliminate toxic ammonia on contact. If you have ordered a precultured BIO-Wheel, it will be delivered in a separate container on a prearranged date.At this time, you should first assemble and install the BIO- Wheel Module and then add product. Remember…the ML-24BW(2) BIO-Wheels are located in the Sump Chamber below the display tank.

Shut Down the System.
Open Sump Access Panel.
Remove the top section of the Protein Skimmer by separating the Froth Cup from the Contact Chamber and disconnecting the Drain Hose from the Drain Port. Set aside.
Remove the Prefilter Media Tray (slides out).
Remove the Carbon Filter Box. Set aside.
Place precultured BIO-Wheels in Lower BIO-Wheel Housings. Tray guides will ensure correct positioning.
Place Carbon Filter Box over BIO-Wheel and on top of Lower BIO-Wheel Housing.
Replace the blue polyfiber Prefilter Pad inside the Prefilter Media Tray.
Slide the Prefilter Media Tray into place above the Carbon Filter Box.
Replace top section of the Protein Skimmer and reconnect the Drain Hose to the Drain Port with the Hose Clamp.
Restart system.

ADDING ANIMALS

Lobsters

Set salinity. Adjust water temperature (50°F). Before introducing new lobsters into the system, dip each lobster and rinse it thoroughly in a bucket of saltwater. Dipping removes accumulated shipping debris and prevents lobsters from fouling the tank.
Never use freshwater for lobster dips…it will kill the lobsters.
NOTE : Do not leave lobsters unattended in a purging container for any length of time without oxygenating water. They may suffocate.
For best results, rinse water should be taken from the established display tank, discarded after use, and replenished according to guidelines on pg. 14.

Fin Fish

Because fin fish are susceptible to temperature shock, it is important to avoid placing new fish in the water much colder than that in which they were shipped.
One day before the arrival of the new fish, water in the display tank should be set to the expected temperature of the water in the delivery vehicle. After fin fish are added, reset the thermostat and bring the water down to the proper setting of 50°F.
NOTE : Due to water conditions in some areas, it may be necessary to perform weekly water changes for freshwater tanks.

The recommended temperature setting is for North American Lobster (Homarus Americanus) and some fin fish. When using tanks for other species, adjust the temperature as necessary for that particular species.

MAINTENANCE

Routine maintenance must be performed. The procedures listed below are neither difficult nor time-consuming. They will keep your system clean, your stock healthy. Failure to follow these simple maintenance steps will adversely affect system performance. This could lead to premature failure of some components and loss of stock. We recommend setting up a maintenance log to track the procedure.

Daily

Check the tank for fatalities and weak or damaged stock. Remove immediately.
Check Water Pump and BIO-Wheel Operation.
Observe the flow of water to the BIO-Wheel Assembly. Make sure that water flow to the BIO-Wheel is not blocked or restricted in any way. The BIO-Wheel should rotate freely and remain wet at all times. Speed of rotation is not important. If a BIO-Wheel is turning -regardless of the rate – it is working.
NOTE :A properly cultured BIO-Wheel is brown or discolored. There is no reason to clean a BIO-Wheel or replace it – unless it is damaged. If removed from the system, make sure that it is kept moist and exposed to air until you reinstall it. If a BIO-Wheel is allowed to dry out or is inadvertently exposed to a contaminant, the culture may be destroyed. A precultured replacement can be purchased directly from Marineland Customer Service (see back page).
The ML-24BW(2) features a Water Level Indicator Light at the back center of the display base. This light will glow red when the water level is below the desired level. If the water level is low and/or flow interruption is evident, make sure all Intake Valves are open and check the Pump Intake (in the Sump) for obstructions. If no obstructions are found, consult the Troubleshooting Guidelines section in this manual.

Never Run Pumps Dry!
This will cause them to fail and result in costly replacement.

Weekly

Clean or Replace BIO-Wheel Prefilter Pads and Replace Carbon Filter Packs.
Clogged filters do not collect waste. Uncollected waste is returned to the aquarium and will reduce system efficiency. In addition, keeping the Prefilter Pad and Carbon Filter Pack clean and unrestricted is critical to the successful operation of the BIO-Wheels. They must receive clean, prefiltered water to keep their bacteria healthy and thriving.
To change Prefilter Pads and Carbon Filter Packs, follow the instructions in the preceding Installing BIO-Wheel section. Rinse or discard used pads. Replace Carbon Filter Packs and rinse out Filter Trays before replacing.
NOTE : Remember to thoroughly rinse the Carbon Filter Pack until the water runs clear.
Wipe Down All Exterior Casing Surfaces
A vinegar/water solution (3 tablespoons vinegar to a pint of water) may be used with a clean rag or paper towel. Never use chemicals, soaps, detergents or harsh abrasives on any part of the system. Do not use cleaners inside or near the tanks at any time.

Warning : Never spray insecticides within 20 feet of your tank system. The resulting contamination could destroy your product and your bio-logical filter as well. If you must use insecticides, be careful to turn off the system and cover the open sump until the odor has cleared from the area completely. And don’t forget to turn the system back on.

Inspect the Display Tank and Sump for Algae Growth.
Algae spores enter the system naturally via tank inhabitants and light allows them to grow. Although your system’s UV Disinfection Unit works to eliminate algae spores, the more light you have, the greater the potential for algae growth. To remove algae, simply wipe inside tank surface with a cloth, algae scraper or acrylic cleaning pad. NEVER use soap or metal scouring pads. Maintain a separate cloth only for the tanks. It should be kept clean and isolated from other departments so that it does not become contaminated by multiple-task use.

Clean Protein Skimmer Froth Cup/Foam Separator
To ensure proper operation, Froth Cup and Foam Separator should be cleaned every week with warm water.
To remove the Froth Cup and Foam Separator:

Shut down the system.
Remove Protein Skimmer Discharge Tube from Drain Port (A).
Remove (lift up) Froth Cup from ContactChamber (B).
Clean Froth Cup and Foam Separator (C).
Return Cup and Separator to position atop the Contact Chamber.
NOTE : Make sure that a good seal forms around Cup and Chamber.
Reconnect the Protein Skimmer Discharge Tube to the Drain Port.
Restart system. Inspect the Skimmer for leaks.
Replace the Sump Access Panel.

Monthly

Clean Refrigeration Unit Condenser Intake Screen To guard against overheating and system failure, Refrigeration Condenser Intake Screen should be brushed (shown) or blown clean. This eliminates accumulated dust and prevents clogging.

As needed
Replace the Fluorescent Display Lamp

Dry hands thoroughly.
Turn the light switch off and disconnect the light terminals (arrow).
Lift Double Lid Holder (A). Grasping the lamp firmly in the center, pull forward and away from the Outer Housing Clamps (B).
Remove Lamp Shield “Boot.”
Using an Allen Wrench, unscrew the End Bolt and carefully slide the fluorescent lamp from the Lamp Shield.
Carefully grasp the Lamp at one end. Press out and lift up to remove from Inner Housing Mounts. Discard the used lamp.
Install new lamp by gently pressing ends into Inner Housing Mounts. Reverse process to restore lamp to operation
