Been swimming for three days. I have learned to keep the solar cover off on sunny days, so the water will get warm. My ph is around 7.3 FC is 4 and CC is .5 so TC is 4.5 if I have this right. CYA is a little more than 40. I have a small air leak that Ted "waste" found. I will fix it next year. One question is with this air leak shooting bubbles out of the eyeballs, will this effect ph? thanks filix.
