Alright so me and my buddy are wanting to set up a frag tank. I have a empty 55 gallon tank sitting empty right now that i was thinking of using. What would you guys recommend for equipment i was thinking a 20 gallon sump and of course heater, power heads and skimmer. What would be the best lighting? Also I'm planning on using egg crate on the bottom with pvc legs to raise it up to get good flow on the bottom of the tank. Since its not like a regular tank with all the live rock and sand what do i use for the biological filtration?
