White flakes in water

[steveinaz]

Well, I've got a serious case of anal-cranium disease. Checked my CYA last night, it's in the 45-50ppm range. A trip to Walmart will fix that tonight. I have re-run all my tests, I guess some of my results were out of date. I usually run all tests in the spring, and then just test Chlorine/pH throughout the swim season. I'm also going to replace a bunch of my reagents this evening.

My pool is so easy to care for, but it's lulled me into a false sense of security. Let me get some numbers normalized, and go from there. Right now here are the numbers (tested, again, last night):

FC=3-5ppm typically
CC=0
pH=7.6 but requires 1/2 cup acid every other day to maintain
CH=710ppm
TA=180ppm
CYA=45-50ppm
Salt=2600ppm (2250-2750 recommended)
Water tmp @ testing=86 degrees

I'll bring the CYA up to 80ppm, and I'm beating down the TA. This fall I'll do a sizable drain to lower CH. I'm also going to replace the QuikChlor SWCG with an Aqua Rite XL. In spite of the numbers, the water has looked/felt great all summer; crystal clear (minus the white flakes), though I believe it was a calcium ridden salt cell that caused that glitch.
