Having a solid amount of experience with freshwater planted/fancy goldfish tanks, I’m about to jump in to a saltwater habitat. I recently picked up a used (but in good condition) 105g oceanic systems RR tank, stand and a trickle filter which looks to be about 30 gallons. I will probably convert the dual corner overflows drains into herbies and have the returns enter back over the rim. Is there any feasible way to convert the trickle filter into a sump with filter socks, a refugium and return section with an external pump? I’d like to try mud with algae (chaeto) and future fish food critters (copepods and the like) in the refugium and hold off on a protein skimmer, initially. I like the natural ecology approach to taking care of waste with my freshwater set up and have had consistently stable parameters with very little maintenance. From what I’ve read, this is totally obtainable in a reef/livestock tank, although the methodology differs. Any advice on plumbing and trickle filter/sump conversion is appreciated.
