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):
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.
