Hey Rollin Thunder, I think you told me a few weeks ago I was in the wrong part of VA cause your water was warmer than mine, but now I can turn it around cause your electric is so high :lol: one of the few advantages of living in the sticks! ha
Anyway, I was running 24/7 with Baquacil and still lost that battle to pink slime (hence my membership and incessant questioning on this forum while switching to BBB and then SWG). With that 24/7 last summer, and using my AquaCal heat pump (w/solar cover) to warm up the water at the beginning/end of season, my bill shot from around normally 200 or less to about twice that.
This year, I've dropped to running the pump 9am-9pm, but I think I'll follow JasonLion and Waterbear's lead and try something like a 5/3 split (or maybe 7/3 or 6/4 if the kids are in the pool all day)...I have a timer for the main pump, but I'll have to fit the Legend Vac into the schedule during the ON times.
BTW - Sabot, not sure why you'd have to run your Legend more than maybe 2 hours/day? I used to run mine 3 or 4 (or more) hours per day, but now I'm down to maybe 2 or so...just a thought, you may want to try that, since that booster pump is probably using alot of energy also.
