looking at building one for my new tank, but details seem to be hard to find. I would want one to run 24/7 not just after water changes. my idea would be to have it as a secondary filter. have a split on both of my over flows to feed it and then it go back into the sump after. this wont filter 100% of my water but should make a big difference over time.
but im trying to figure out how to build one that can run 24/7 any suggestions?
