Filter for how long?

Until recently I've been under the assumption that a filter should be run long enough each day to turn over the volume of water in the pool. I'm wondering what the minimum time I should be using now. I have a 2hp single speed pump and about 30k gallons of water. I am currently running 8 hours a day, but I would like to reduce the time to save some money if I can.

See my thread answered well by a few TFP Experts. If your pool is clear and chemicals in balance, you are just mixing the water when running the pump. Get your single speed on a timer for best results and run it 4-8 hours per day.
