Total alkalinity (TAC) increaser tablets Impact Tac +Tab
TAC booster – 20 g tablets
“I help you stabilise your pH!”
TAC (total alkalinity) is an essential parameter of your pool water's chemical balance and is essential for keeping the pH stable. Tac +Tab raises the total alkalinity of your pool and helps balance the water. It is intended to stabilise the pool pH when it fluctuates a lot, and it promotes effective flocculation and clarification.
The ideal TAC value for good pH stability is between 80 and 150 ppm. Non-foaming and highly concentrated in active matter, Tac +Tab corrects the TAC quickly and regulates the water balance.
How to use
- Place 1 tablet in the skimmer to raise the TAC by 4 ppm per 10 m³ of water.
- Leave the filtration running for 24 hours.
- Check the value obtained and readjust if needed.
- To avoid cloudiness, do not overdose.
- Besides the TAC, test the pool pH regularly and keep it between 7.0 and 7.4: a stable pH and an optimised TAC keep the water clear and healthy.
Good to know
- Essential at the start of the season, after heavy rain or after any fresh-water top-up.
- Leaves no residue and is a handy replacement for powder products.
- Suitable for all pools: in-ground or above-ground, liner or shell.
