Aquablanc – Active O2 Non-Chlorine for Hot Tubs

This non-chlorine active oxygen treatment offers users a non-halogen alternative (i.e. no chlorine or bromine), for effective sanitization of hot tub/spa water. Aquablanc Active O2 treated hot tubs/spas provide pure, gentle and safe water, without the attendant smells associated with chlorine.

WATER TESTING WiTH AQUABLANC ACTIVE O2
Using Aquablanc 3 way test strips or an Active Oxygen Pooltester, you are able to quickly and accurately assess water conditions and make necessary chemical adjustments. Test an hour after application of O2 tablets

5 – 10 ppm one hour after application
ppm = parts per million

THE IMPORTANCE OF CIRCULATION ANd FILTRATION

Most hot tubs/spas include a pump and filter (either sand or cartridge) as standard. It is a combination of circulating water through the filter, together with good chemical water treatment that helps maintain clear, clean and healthy water. The Aquablanc O2
system, will for example, breakdown bacteria in organic matters and wastes but the resulting by-product needs to be removed effectively via the filtration plant.

PH AND TOTAL ALkALINITY

PH is a measured scale 0 – 14, measuring acidic or alkali conditions respectively. pH7 is neutral. Ideal Aquablanc readings are 7.0 – 7.4 for optimal bathing conditions alongside most effective chemical use and hot tub/ spa equipment protection.
Total alkalinity is a measure of the waters ability to resist or hold pH levels – if you like, it is a ‘buffer’ for pH. Low alkalinity can lead to rapidly changeable pH conditions, and conversely high alkalinity can lead to ‘stubborn’ pH levels.
Use pH Minus to reduce pH and pH Plus to increase pH. Use TA Plus to increase total alkalinity.

High pH
High Alkalinity| Scale formation
Skin/eye irritation
Reduced Active Oxygen effectiveness
Ideal pH and Alkalinity| O.k
Low pH
Low Alkalinity| Plant corrosion – e.g. metals
Bather discomfort, unpleasant smells
Active Oxygen quickly used up

ROUTINE OXIDISATION/SHOCk TREATMENT

It is considered increasingly good practise to regularly (weekly or fortnightly), oxidise hot tub/ water to break down contamination or non- filterable waste (body oils, fats, grease etc), for more effective removal via the filter.

Whilst the use of a double dose of O2 tablets will fulfil this purpose, as chlorines are also compatible with Aquablanc Active O2 ,then Spa Fusion is a convenient sachet of oxidiser also tailored for this purpose.

CONVERTING OR CHANGING TO AQUABLANC ACTIVE O2
Before converting your hot tub/spa to Aquablanc O2, best results are obtained when spas are being refilled for the first time or after draining and then on re-filling.

COMMISSIONING A NEW HOT TUB ON ACTIVE O2
This requires an initial chlorine dose of 50 mg/l (ppm) for an hour, or 20 mg/l (ppm) for 2 hours to ensure any contamination from factory wet tests or whilst hot tubs are in transit is eradicated. In practice 20 mg/l for 2 hours is much more practicable as  waiting for chlorine to reduce after these commissioning dosages, can in any event take a while. Only proceed to move your hot tub/spa to Aquablanc O2 when chlorine levels are 5 mg/l (ppm) or below.

CONVERTING TO AQUABlANC ACTIVE O2
On refilling a hot tub/spa, first shock treat with chlorine or Spa Fusion to 5 – 10 ppm, and allow chlorine levels to fall to 5 mg/l (ppm) or below prior to commencing with the Active O2 system.

DOSING AQUABLANC O2 TABLETS/ A COMBINATION LIQUID
The Active O2 system is a dual action system requiring a weekly dose (or weekly top up) with A Combination Liquid, combined with O2 Tablets dosing via appropriate floating dispenser prior to bathing (or otherwise weekly).
Add the A combination liquid direct to the spa whilst the circulation system is running. Add the O2 tablets via a floating dispenser prior to bathing (or weekly otherwise).

A Combination Liquid dosing (per 1,500 ltr)

Initial dose| Weekly dose
60ml| 15ml
Active O2 Tablets dosing (per 1,500 ltr)

Initial dose| Prior to spa use (or weekly)
2 Tablets| 1 Tablet

OTHER SPA / HOT TUB TIPS

Foam control:| Warmer waters may quickly collect body oils, cosmetics etc before the filter/cartridge can remove them, leading to unsightly foaming. Use a Spa Foam remover (AquaSPArkle FoamAway) to control this problem.
---|---
draining/Refilling:| Over time water absorbs minerals and chemicals contributing to increasing Total dissolved Solids (TdS) levels. High TdS levels reduce chemical efficiencies and make it hard to maintain water correctly. To avoid this, as a guide, drain and refill every 4 – 6 weeks.
cleaning cartridges:| Filter efficiency is impaired when cartridges get too dirty and these should be cleaned weekly with water to remove loose debris and chemically cleaned monthly (using AquaSPArkle Immerse or Cartridge Cleaner). As a tip it is useful to have a spare cartridge to use whilst the other is being cleaned.

SAFETY

General spa safety

• do not allow water temperatures to exceed 40 °C (lower for children).
• do not leave children or non-swimmers unattended.
• do not overload the spa.
• do not use electrical appliances near water.
• Use plastic and not glass around the Spa.
• do not drink alcoholic beverages before or during use of Spa’s.
• If you are pregnant, have high blood pressure or cardiovascular condition then consult your doctor before using Spa’s.
• When changing (dirty) filter cartridges, wear gloves.

General Chemical safety

• Always read the instruction label on chemical products.
• Always adhere to the instructions printed on the product label.
• Always handle chemicals in a well ventilated area, preferably outdoors.
• Always keep chemicals out of the reach of children.
• Always wash hands after handling chemicals.
• Always store chemicals in a cool, dry place.
• Always put the lids back on chemical containers.
• When pre-dissolving products always use a clean container.
• never use chemicals that don’t have an instruction label.
• never mix chemicals.
• never dose chemicals when there are bathers in the spa.

Problem solving Chart – spas

if time to drain/refill’
Too much Chlorine after Oxidation/Shock
treatment| Overdose| Allow time to naturally dissipate or buy a chlorine reducer
pH hard to control| Alkalinity too low| Seek advice on how to raise total alkalinity
Cannot maintain adequate sanitiser
levels| “Sanitiser” demand of water too high at start up, after holidays or due to excess contamination or neglect| Shock dose with double dose O2 tablets or other products
in routine oxidation recommendations
Foaming Water| Oils/ detergents present| Use Spa FoamAway
Cloudy Water| Poor chemical controls or Inadequate filtration| Clean cartridge, or consider if time to drain and refill. Retest water, and add chemicals if necessary
Rough sides/edges| Scale formation| Ensure pH levels are correct and if scale persists use  ScaleAway to stop calcium precipitating out of the water
No colour change on test strip dip test| Too high chlorine leading to bleaching of indicator pads (over 15 ppm chlorine)| Check expiry date on test strips. Wait for sanitiser level to drop and re-test
Test results vary (spas)| Air bubbles can increase pH and reduce alkalinity temporarily| Test when the system is turned ‘off’ for true results
Waterline grease contamination| Detergents/oils/ greases present| Use Spa Perfect to eliminate contamination or clean with Spa Surface cleaner
