We'd be glad to assist you. Is the pool water clear or is it cloudy/green?
If the pool water is clear, the cartridge could be packed with oils that can't be removed from a normal hose down. We'd recommend soaking the cartridge in a filter cleaner. If the problem persists, you may need to replace the cartridge.
