It looks like I am adding 32-38oz of muratic acid (31% strength) every 4 days while using my autopilot SWG. Is this add a normal frequency and a normal amount?
This is my first full year with the SWG since I installed it at the end of the last season. I am attempting to follow waterbear's sticky on SWG water balance, adding acid at a pH of 7.8 to lower it 7.5 to 7.6 and then allowing it to drift up, but it looks like it drifts up 1 pH pt per day. Here are my present chemistry values as of today (6/11/08). Note I last added acid on 6/7/08 (32 oz):
FC 2.9ppm
TC 3.0ppm
pH 7.7
TA 77ppm
CYA 65ppm
CH 310ppm
water temp 88F
salt at 3000ppm
pool gets full sun all day (no shade)
30,000 IG concrete pool
Autopilot set at 55%, power level 2, and FC has been steady for last 3 days.
