I have a 24' AG (13,500 gal.) with a Hayward pump and sand filter. I recently had an electronic timer installed, so I can automate the times the filter is running. How long, and what time of day should I be running the filter. Right now it's rather cold in upstate NY, so the solar cover is on and we're not using it everyday. Any advice appreciated. thx.
If you look at older posts in this section you should be able to find a calculation to determine roughly how long it would take to pump 13500 gallons through your filter and you should run your pump for at least 2 times that amount. I have the same size pool and it works out to about 4 hours for me so I run my pump for about 8.5 hours.
The schedule really is up to you. I run it four hours in the morning from about 9 to 1 then four and a half hours from about 5 to 9:30 so that when I get home from work (and after the kids are in bed) I can add chlorine and let it circulate for awhile. If you're using a solar heater, you will want to get as much pump time while the sun is shining on the heater especially at this time of year. The bottom line is as long as you run the pump for the right number of hours, there's no wrong way to schedule the time.
