CYA 20
I think I've got a problem? One month ago I had a CYA reading of 50. Today I had a CYA reading of 20...both readings were from the the TF-100 test kit. We are probably putting in about 1-2 inches of new water every other day due to what we thought was evaporation. Do you think it's possibly a leak and not evaporation...and that's what caused the dramatic decrease in my CYA level? Could I be replacing that much water thus causing that much of a decrease in my CYA?
Thanks,
Alan
