Thanks again. My next "project" will be to add borates. I've already done the math and bought 10 boxes of Borax, 3 gallons of muriatic acid and I've been looking around my house for devices for D.I.Y. aeration as it seems the hardest part of adding borates will be the first step of bringing my TA down from 130 ppm. I'll probably start that next week as we are having company over the weekend.
One last question, though. Given that my CYA prematurely tested around 56-ish, 5 hours of direct sun per day and "the usual" bather load, how long would you guess it might take FC to drift down to 5?
