How long to run pump

[mroll]

I'd love answer to this too. My pool is much smaller than yours (5700 Gallons) and I have a Haywood 3/4 HP Power Flo matrix Pump on a DE Filter. Dealer told me about 3 hours and thats what I've been doing and pool looks great. Electrician is Going to put it on a timer cause I often forget to turn it off after 3 hours!! Electricity is WAY TOO high here for me to run it more than 5,6 hours per day!

I believe you run your pump/filter long enough to filter all your water once. The amount of time will vary depending on the volume of your pool. I have a 24,000 gallon IG pool so it usually takes me around 8 hours to filter the entire pool. I alter when my pump/filter is on. On days where I don't need to add bleach in the evening, I let it run while I am at work. On days when I know I'll bleach in the evening, I don't run the pump/filter during the day. I'll wait until I get home from work then run the filter/pump until morning.
