It's hot and it's time to keep cool in the swimming pool.  Is your pool water green or cloudy?  Take a water sample to the local pool store to ensure your water has all the proper chemicals.  After that if there's still a problem, it's a good bet that your POOL FILTER may need cleaning or replacement.  Turn off the pool pump and open up your filter.  For a DE filter check to ensure there are no tears in the DE Grids.  For a cartridge filter, check the pressure gauge (should be 10-14 if OK) and the filter to see if it's dirty and clean it off if necessary.  If after cleaning the pressure doesn't go down to the 10-14 range it's probably time for a new pool filter.
