Aquarium Advice Freak
I am setting up a 180g Saltwater FOWLR. I have been weighing the pros/cons of canister, regular sump (bio balls, skimmer), and Refugium (mud/rock,algae, skimmer). Depending upon who you talk to they recommend and swear by one vs the other. Can someone run down the pros/cons of all three approaches, if there is a other approach, that too.
