ACTIVE
OXYGEN
FREQUENTLY ASKED QUESTIONS
What is Active Oxygen?
Active Oxygen sanitation is based on the use of potassium monopersulphate tablets. Potassium monopersulphate works in much the same way as chlorine or bromine in that it kills bacteria and breaks down bather waste. However, unlike chlorine or bromine, monopersulphates don't produce by-products that irritate the skin or eyes and cause nasty smells. The tablets are used in conjunction with a weekly does of liquid activator which also acts as an algaecide.
How
do I run my tub using Active Oxygen?
Step 1 Drain your spa, clean, refill and check the water balance
With any sanitizer system you should make sure that your water is adequately balanced to protect your equipment and ensure that the water remains comfortable to bathe in. The Total Alkalinity should be in the range 80 – 160 ppm, the pH should be in the range 7.0 – 7.4 and the Calcium Hardness should be at least 100 ppm. In the event that your fresh water is outside this range you should use adjusters to first adjust the total alkalinity, then the pH and finally the Calcium Hardness.

[Note: With any water treatment system we recommend the use ofa pipecleaner, such as Spa Flush or jetONE, at every water change to remove bio-film and other deposits from the plumbing and equipment without the use of harsh or toxic chemicals.]
Step 2 - Apply an initial dose of Active Oxygen Liquid
Apply an initial does of Bayroplus Spa or AquaBlanc A Combination liquid at the dosage recommended on the bottle.
Step 3 - Every time you use your tub
Add 1 Aquablanc O2 Tablet or 1 – 2 Bayroklar Spa Tablet(s), depending on the size of your spa. It is better to add the tablets via a floating dispenser.
Use an Active Oxygen Test Kit or Test Strips to ensure that the potassium monopersulphate concentration in the water is in the range 5.0 - 8.0 mg / litre. (Note that the monopersulphate concentration should not fall below 5 mg / litre while the tub is in use.)
Step 4 Once per Week
Test and adjust the water balance, if necessary.
Re-apply the Bayroplus Spa or AquaBlanc A Combination liquid at the dosage recommended on the bottle.

Is there anything else that I have to do?
Yes. Filtration....
Filtration is another vital part of keeping your spa water crystal clear. In common with any sanitizer system, you should make certain that your filtering cycle is adequate for your spa volume and usage, clean your filter regularly using a proprietary filter cleaner and replace it every 6 - 12 months.
Filters last longer if they are allowed to dry out properly between uses so it's a good idea to keep a spare and rotate them.
