Whenever a pool owner states that their water flow is reduced, and gets better either on recirculate or immediately after a backwash, we think of algae. Algae, even in it's transparent form, can clog-up a filter very fast. How does the water look? Is it cloudy at all? How are you testing your water and how are you chlorinating? can you provide a full set of test results?
