I just upgraded form a 30 gal FOWLR
tank to a 72 gal FOWLR
tank and installed a WDF with this setup. I have two questions related to it's setup... Question #1- Should I shorten the hose to the sump, it is a little too long, not unmanageable, but I can be OCD about wires and hoses, etc. and Question # 2 - Can I put a 90 elbow on the hose into the sump instead of going into the top straight down? The sump doesnt sit directly under the bulkhead fittings and I find the weight of the hose with water coming down is kind of lifting the sump cover where it enters over the bio balls - or does this impede flow and I should leave it as is and weight the cover down? Thanks for any suggestions or others experiences.
