As of now, in my FOWLR I have 75 lbs of LR, a 5" sandbed, a remora skimmer i am selling to upgrade to the remora pro with a mag. I also have an eheim classic, a euro-reef sump/refugium, two penguin HOB filters and 2 small in tank canister filters I use to promote more circulation. My question is, since I am switching to reef, should i get rid of the HOB and Canister filters, since they are nitrate traps? or should i just try filling them with chemi pure, or just let them run empty to increase water volume and circulation? Should the remora pro skimmer and sump be enough filtration?
