Kathy--sorry you're having such a frustrating experience. I haven't read every post on this thread so I apologize if someone already asked...what kind of filter do you have? Is it in good working condition? Have you backwashed and dismantled the filter to clean it well? You can run your pump until doomsday but without a good, clean filter you may be just be recycling silt back into the pool. (i.e., If you have a DE filter that has deteriorated the filter "fins" could have holes that let debris back into the pool. If the filter has holes you may not notice an increase in pressure that would indicate time to backwash.) Good luck and don't give up yet!
