I am a very happy BBB user thanks to TFP. Very stable pH and TA (Liquidator as well, with solid results)
Opened the pool after last year's use of Dichlor (before BBB) with CYA of 110. Drained the pool water to start season at 85. A few months it was own to 75 and now 55, which I know is a good level. But why the decrease?
I can state categorically that there is extremely little splashout. Of course there is evaporation, rain water fill, and tap water fill
Is there another chemical reaction that is eating up CYA? Is there need to worry or just add Dichlor when CYA gets below 50?
