Hello, I'm looking to get some insight on setting up my new refuge. I have a 100 gallon fowlr that has had a 25 gallon sump for 7 years. I just bought a new refuge that has a 4 separate compartments. I now have a skimmer and a compartment for growing algae or mangrove as well.. I'd like to make this tank able to sustain corals in the near future. what would you all suggest that I'd grow in that refuge to eventually sustain coral and LR?? I only have 4 hardy fish and some snails at this time in the tank that have been there since day 1. Thanks in advance.
