Well, darn it. If I hadn't been away from the pool Tue., I might have been done. ( I'm not complaining really, I'll trade a new grandson for algae any day !) Kim, I think I could actually tell if a nickel were heads or tails if I got real close to the top of the water . BUT, FC dropped from 34 to 26.5 overnight, CC still at .5, so more bleach today. The problem I'm having is this darn rain. Up to the top of the skimmer again this morning, calling for another 1" to 1/2" through tomorrow. Supposed to dry off some after tomorrow. Unless you think otherwise, I am going to drain about two inches off, then bring it back up to shock level again. I'm thinking I might bump it up higher than 33 with the coming rain. Maybe 2 jugs instead of 1.3 or am I pushing limits still assuming CYA is 85. With the added rain it may have dropped. Don't trust myself testing it with the clouds and rain
