Raddish-
Was using pucks from WalMart(not sure what kind of chlorine in them).My water starting looking cloudy right before the 4th. I had my water tested at the pool store and all of my levels were good. I can't remeber the exact numbers but all was good. My CYA was fine too.They sold me Green to Clean because I thought I was getting algae. I shocked used the Green to Clean and shocked again with the powder shock. The water was looking better on the 4th. We had a big bbq for the and lots of pool use. The next day the water was very cloudy,bluish-grey. I kept shocking and leaving the filter running and nothing. My chlorine would not keep. The water is not cloudy anymore, but it is green. Yesterday I had the water tested at the same pool store as before and my CYA was zero. I meant to ask does that seem right. How would I lose my CYA so quickly. We did have A LOT of rain, it's Monsoon Season here in Tucson.Would that cause the CYA do totally diminish?
