Hi, I am looking to create a sump and refugium for a new 75 or 90 gallon chichlid tank. I have a pretty good idea of how to design it, I plan to use some of the media you would put in a top hanging filter (sponge, charcoal, bio media). Most designs I have seen put the filter media before the plants, it seems to me it would be better suited as the last stage to keep the pump area debris free. Am I missing something?
Thanks!
Thanks!
