not that in my area of canada we'll run pool during the winter, but..i'm in a similar situation in regards to freezing..at this point it's still nice enough overnight that my 8am to 2pm, 8pm to 2am cycle is fine..but, i'm heading out of town for balance of the week and it's possible it will dip to 29-30 overnight by later this week. my pool guy says that supposedly a pool with it's volume of water should not freeze substantially until below -10C (enough to freeze pipes) but darned if i'm taking any chances..it's not his pool, is it!

so, the main thing i'm doing is i've switched my cycle as of tonight for the pump to go from midnight to 6am...then a 10am to 4pm cycle. my main concern is avoiding overnight temp drops..my heater is still switched on..if it gets really cold, i might run into a day's worth of running where it may have to kick in, maybe not..and the lowest temp on it is 70 so even if temps were going to freezing during my "pump off cycle" with a cover on, i very much expect the pool will retain enough heat to not freeze. then i'll shut it down this weekend when i return. that's my plan, anyway

summers over..sigh.
