YOU ONLY NEED VERY SMALL QUANTITIES OF CYA. Are you sure you need it? Most chlorine sold for pools is already stabilised with CYA.
Q: Do I need cyanuric acid?
A. Short answer: If your pool is outside and if you use a salt water chlorinator during the hours of sunlight, YES, you do.
Longer answer: Read our short article before you buy it..
Cyanuric Acid (CYA)
Prevents 'burn off' by sunlight of non-stabilised chlorine in swimming pools. It binds to free chlorine and releases it slowly, extending the time needed to deplete each dose of sanitizer. Particularly effective in pools equipped with salt water chlorination systems that run during daylight. Not needed for indoor pools.
For pools with saltwater chlorinators, the best results are obtained at a pH of 7.2.
Recommended maximum concentration of CYA: 50 ppm
YOU ONLY NEED VERY SMALL QUANTITIES OF CYA.
As a rough guide, For a 200,000 litre (200m3) pool, for example a pool 10 x 20 metres, 6 Kg of CYA would be sufficient to raise the CYA level from 0 to 50 ppm. CYA does not get used up - its only loss is through backwashing and heavy dilution of the water from rain, and topping up.
A medium sized domestic pool of around 4 x 10m, average depth 1m, and using a salt water chlorinator, would need only 1 Kg of CYA to raise the CYA from 0 - 30ppm. Regular maintenance requires only a tiny fraction of this amount.
