I needed to raise my CYA last week. I went to Walmart and bought the hth brand stabilizer & conditioner. I have read other posts that says make sure the stabilizer is 99% cyanuric acid. What I bought is only 96% with 4% inert ingredients. My question is what brand should I buy that has the 99% cyanuric acid and what stores should I be looking in or is what I bought okay to use?
It has raised my CYA but not as much as it should have by the poolmath chart.
