8 oz Cyanuric Acid Reducer Powder for Pools - Non Polluting 100-Percent Reduce Cyanuric Acid for Commercial and Residential Swimming Pools

Didn't do anything for me. CYA went down 2. That can be explained by the addition of water to the pool. (Topped off). My chlorine level was 5. I've been told by pool care techs that directions must be followed to the letter for all CYA reducers to be effective.

I contacted the company with no response to get an MSDS on this product. I had 0 results on this product . No customer service at all
