Thanks.I understand the fact that lower flow will provide more contact with media, and specifically less potential for bypassing that media... but my instinct is that keeping it clean is likely a better solution.
my concern with lowering the flow is the potential mechanical load it puts onto the system. It just leaves me a bit uncomfortable.
If you see better or similar results lowering the flow, then go for it. I really only do use canister ilters rather than power filters and I normally want as much flow as I can so I don't have the experience you are looking for.
