this upcoming fall i am going to be setting up a 20 gallon nano with your basic live rock and live sand. i plan on keep to percula clowns and a BTA and maybe a cleaner shrimp. i am just going to use hang on filters for the tank and a skilter that i made into a "mini refugium" that is currently on my 55 gallon. it just has live sand and caulerpa growing in it, but works well and will work even better in a 20 gallon. was wondering if anyone knew where i could get some MH for a reasonable price. and does anyone think i should use a
protein skimmer or should the live rock be enough biofiltration, as well as the "mini fuge" to keep the nitrates down? and any other suggestions one might have.
