85-90 CYA in a SWG Pool?

[ideal2545]

Hi All,

I'm still a bit of a noob at reading the CYA chem test but I think that in my SWG pool my CYA is sitting between 85-90. I know that the recommended level is 70-80. Is this discrepancy enough to worry about or should I dump water? I suppose I could try to maintain a slightly higher FC (maybe in the 7 range?)

90 ppm CYA is fine. Keep your FC at or above 7.5% of your CYA (7 ppm).
