Hi, We recently installed an Intex 16' X 48" AG pool. We've had a couple Intex before and have not had much success keeping algae at bay, so this time I did a lot of research (mostly on this site, thanks) and hoped to get it right. We filled the pool on April 29 and have tried to maintain my levels. I'm using the stock pump (not SWG) which is approx. 1500 GPH turnover. I followed the directions for "Beginners Guide for Seasonal/Temporary Pools." However, I think my CYA may be too high. I did some reading on here and bought the 'standard' to see what 50 ppm looked like, but when I do the test on the 'standard' it comes out high as well. Other than the CYA 'problem,' I think things are okay. But I'm concerned because I understand how out of whack things can get with high CYA. My levels are listed below. I guess my questions are, if I have CC equal to 0 (or close) does that mean I do not have any algae growing? Is it normal for pH to go up when a large amount of Chlorox is added? I'm not sure if I shocked correctly either since my CC is usually 0? Do my numbers seem at all on target or am I doing something wrong? The water looks pretty good except I have some white/clearish flakes on the surface. We had some rain recently and it seemed like a ton of ants came out of my neighbors tree into the pool, so I think the white/clear stuff may be wing material (yuck). I skim and skim, but can't seem to get it all out. I don't think the pump is doing a good enough job either. I'm thinking of replacing it. Any suggestions? Sorry this is so long. I'm trying really hard to get this right. Thanks in advance for the help. Karen
