DIY Orlando Pool Repair and Care ~ Step 8: Clean Filter

Proper filtration will take care of cloudy water and rapid algae growth. The more filtration the better, especially when the water gets warm.

For a screened-in pool under 20,000 gallons you will need to run your filter at least 8 to 10 hours a day. For larger pools, unscreened pools or pools with frequent and multiple users, 12 to 14 hours per day is recommended.

Most filter manufacturers recommend cleaning your filter using the pressure dirt loading method. To do this, clean the filter and record the pressure gauge reading when the pump is on and water is at optimal flow. When your filter gauge reads 8–10 PSI above the clean pressure reading, you will need to clean your filter. For Example: You clean your filter and record a pressure reading of 15 PSI, check your pressure weekly and when your gauge reads 23 PSI you need to clean your filter. This dirt loading method actually polishes your water giving you a sparkling pool.
