Before learning a lot from this site I had a bad green algae problem where I went through numerous shockings across three weeks using trichlor, dichlor, etc and used some Cheleated copper.....After following a post in here and keeping FC at 15 (from Bleach) for 3 days it dissappeared!!!......Algae is gone but a bluish color exits to where I cant see the bottom....I took my water to a pool store (TFT kit on xmas list ) and my specs are as follows:
CYA 100+ (I WAS SHOCKED I DIDNT PUT ANY CYA IN FOR OVER 3 MONTHS)
Ch: ? Sorry that did not write that one down.
I realize now after my education from this site and the pool calculator the side effects of large quanities of certain shock chemicals adds CYA. Short of a drain/rebalance is there any side effects running with this 100 CYA level and just keeping my FC level higher? IF so, a really high CYA using Bens best guesstimate is it practical at 100CYA and the 8FC level??? Does it require a lot more bleach to move FC levels with this kind of ratio? If it safe for my kids/bathing suits??? IF the only side effect is just higher doses of chemicals then it may be cheaper to do a partial drain/refill....I did drain about 10% of the pool to help and the PH dropped to in range now 7.6
---Also, Is my funny colored water due to this from my high CYA or Copper from the Algaecides? Any help would be greatly appreciated.
Oh, as a side note to support the teachings here DO NOT trust test strips.....My numbers were way off and my CYA was not even registering!!!!! I even made them test twice at the pool store to verify this out of control CYA (I was between 0 and 30), and my PH was showing low (7.2, theirs was 7.8 ) this was from the same bottle of water both test methods!!!
