Good quality

Cyanuric acid levels in my pool have been consistently high throughout the season, with the only remedy advised being to drain, or at least drastically lower the water level, then refill. This product did the job for much less fuss and cost in water and worry. Not even the pool supply store was aware of it.

Wonderful

I like what I read about the product, and its usage. I will use it to see if it will really help neutralizing or reducing cyanuric acid in swimming pools without wasting a lot of water.

good product at reasonable price

The product was very slow to work in my pool: 8000 gallon. Dumped in 1 bag - nothing. Dumped in a second bag a week later  - nothing. 3 weeks later acid dropped to 50 from 125. Very strange! Acid is back up close to 100 so looking for something better.

Cyanuric acid reducer

Must follow the instructions carefully because it takes time and tight control of chlorine level to work properly.  Too much CA ties up free chlorine.

Chlorine activator

1 package is suppose to lower the CA in our 25,000 gallon pool. It was 150. We added 1 package with 0 results. Added a second package and the cynuratic acid actually went up to 165. This stuff does not work.  I am going to try to get my money back so we'll see if they are willing to do that.

Doesn't work at all

Waste of money used two bags did nothing. Still have chlorine lock

Doesn't work
