I have an in ground pool with a canopy of oaks surrounding it (and that is obviously HUGE problem for keeping my pool clean). I have recently bought a Polaris 360 to help with cleaning the bottom but it is not really helping with the small particles and my filter (cartridge filter) has to be cleaned every 2 or 3 days. My question is would it be advisable to use a classifier even if my water is clear and my chemestry is good? I'm thinking my Polaris will pick up the debris from the bottom....... any advice will be greatly appreciated!
