Thank you! Yes, we have orange filter cartridges every time. Actually our pool pump can only run for about an hour and a half before it is too clogged and orange, so we can't keep it running continuously but have to monitor it. So I think we still have a long way to go before we ever get the pool cleaned up and may not resolve the problem this pool season, but at least we have a better idea of how to fill it without causing this problem next year. Thank you!
