Finally got my TF100.. I really should have gotten that before (long story) but hey, now is better than never. I can't believe how off the pool store tests were and I adjusted my chemicals according to their results while trying to aim for the pool school guidelines for SWG with a CH slightly higher than it recommends (to avoid warranty issues on my equipment).
My pool is a ~20k gallons, vinyl liner. I run a P4 panel, pump on 8 hrs / day and chlorinator was set t0 25%. Here's the result of my tests:
pH = ~7.6 :-D (bang on, same as pool store)
fc = 8.5 so I've lowered my SWG to 15%
cc = 0 :-D
CYA = 45 (low.. pool store had tested it to be 100.. WTF?)
CA = 180 :-D (two pool stores tested it, 125 for first, 180 for 2nd)
TA = 180 (stores tested it to 110 and 125, after initial test at 40 for which they told me to add lots to reach the target of 125 - 150..)
I know how to deal with the fc and CYA but I'm wondering if I should deal with the TA? Too much TA is supposed to raise the pH but I haven't had a problem at all with my pH since I've filled the pool..
Any suggestions?
