Do you have your filter on a timer?

[momofonly]

I don't have a pool yet. I'm in the process of researching an 18 foot round above ground pool. My husband and I are wondering how long a filter needs to be run in the summer. While we were doing research in the local pool store today, we heard a few customers mention that they have their pool filters on a timer. Do most people put the filter on a timer? If so, how long is it set for? Or is it better to run it 24 hours?
Thanks! This is a great forum.

I don't have mine on a timer, because of the tendency around here for evaporation to take the water level too low. During swim season, I turn it on in the morning when I get up, and off when I get ready to go to bed, so it runs somewhere around 12 hours. During the winter I run it overnight when the air temps are below freezing, but otherwise just 2-3 hours a day to circulate chlorine when I need to add it (my pool never closes).

When clearing up an algae bloom or other water problem, the filter needs to be run pretty much 24/7, but otherwise it only really needs to run enough to turn over your pool's water volume once a day--for most pumps/filters, 6 or so hours a day is plenty.

I don't currently, but many summers we do put our pump on a timer to kick on around noon and off around 8pm.

If you can stand it--go for it!

I use a timer and wouldn't want to do without one; one less thing to have to remember. During the season I run it about 14 hours a day; I find this is long enough to keep the pool clean and allow the SWCG enough time to maintain chlorine levels (note that I have a 20k gal IG pool).

Intermatic timer. I run 7-11pm and then 7-12am ...

Intermatic timer hardwired into my breaker box. Runs from 10 PM to 4 AM each night because the rates are 50% less. I have a 2 speed pump and run it on low speed which means it takes just 1/4 or so of the electrical power. I cannot tell in the summers that my pool pump is added to the load because the A/C uses ever so much more power. I run the pump on low speed for an hour or so after a swim session to skim the dog hair off the surface. The timer has definitely improved my life. I don't have to remember to do yet another thing

Our pool builder didn't even offer a pool without a timer -- it's just assumed that the homeowner would want to use a timer, and I see why -- it's just one less thing to remember, one less thing to do. Ours runs 8 hrs a day, all months of the year (I'll run the filtration system if we're swimming after 4pm when the timer shuts off the pump). I'm experimenting with how low I can run the variable speed pump and still maintain crystal clear water. Last summer I ran the pump @ 2750rpms. I started this summer running it at 2000 rpms, and just now dropped it to 1800 rpms. I probably won't go lower than 1800 rpms, as that's running the pump at about half-speed.

I run my filter 24/7 is this bad?
