Re: Flow Problem
This could be a filter problem or more likely, the algea is just clogging up your filter. When the flow drops does the pressure on your DE filter climb? I would backwash frequently (5-8 psi rise) and vacuum to waste if there is a lot of sediment. Do you have a multiport valve? If so, bypass the filter and the flow should not 'fall off' at all (if you need to leave and want to keep water circulating but not risk pump/filter failure from backpressure).
