• What advice is there for treating my pool correctly?

- Preferably treat your pool in the evening: after swimming, add your maintenance products and let the filtration pump run to distribute the treatment evenly through the water.- Never mix concentrated products together. This can be dangerous.- Always add the product to the water, and not the other way around, to avoid any unwanted reaction.- Choose quality products: to guarantee safety and effectiveness, it is recommended to buy from a specialist pool professional.- The advice provided in this analysis is based on the experience and expertise of the Poolyse team, to help you keep your water clear and healthy safely.- A small amount of stabilizer in the water improves how long chlorinated pool products remain effective against the sun's UV rays; in other words, some stabilizer is useful to prevent the sun's rays from eliminating chlorine from the water too quickly.
However, if there is too much stabilizer in the water, chlorine no longer works and the water is over-stabilized (above 50 mg/l, partial renewal is recommended, draining ⅓; above 60 mg/l, significant renewal is recommended, draining ¼).
Why regulate TAC?
- TAC decreases when it rains, when people swim, with jets, waterfalls…
It is the buffer capacity of pool water. (It counteracts sudden variations in pH.)
- Chlorine
Influence of pH on chlorine effectiveness
pH=7.0, chlorine works at 80%
pH=8.0, chlorine works at only 20%
- Green water goes through 3 stages within 48 hours
1: green
2: cloudy
3: crystal clear
