First of all, I'm a solid believer in the BBB method. In fact, I was bragging about my ability to clear up troubled pool water, when a good friend of mine left town - and challenged me to help him out with his pool water.
I know he's been frustrated with light green algae the last few weeks, and he's been throwing a bunch of di-chlor shock into the pool to try and clear it up. I went over tonight, in anticipation of adding some bleach and testing every 30min or so. But, after these test results, I'm a bit confused what to do next.
CYA = 120
I immediately jumped on the high CYA reading, and was all ready to dilute with fresh water, but then I remembered his water is pretty cloudy already. That should drive a higher than actual reading for CYA, correct?
He's got enough FC - maybe it's just gonna take a long time to clear? Any other recommendations?
