So far so good, installed Pool Pilot Digital with SC-60 cell on Sunday 7/11/10, and set it to 50% on Power Level 1, runs 8 hours a day with the pump .Checked the water everyday , FC was between 2-3 ppm and pH was 7.5 , Alk is 100 . It rained alot here last night so I checked this morning , FC was 2 , pH was 7.8. I added Ph Down (I know Muriatic acid is cheaper, but with my crazy kids around , I'll pay for the pH minus) but I wanted to add more FC to the pool , so I put it on " Boost ", tested this evening and the FC was 3.4 , pH still 7.8 , I guess due to the SWG working at 100%. Should I add more pH down tonight or wait overnight and see what happens, should I turn the pump back on and let it "Boost" overnight ? The pool is crystal clear , but I don't want to mess it up while I "learn" the SWG . THANKS
