Hey guys. So I ordered a 220 (72 x 24 x 30) from my LFS and I am excited to get this build going! Right now I have a 54g FOWLR so I'm gonna be converting to reef I think. I only have four fish right now so I have to see how they get along with some test corals before I really dive in. Gonna get some cheap chinese LEDs from ebay and re-use my skimmer and my bio pellet reactor (oversized for current tank). Honestly, I hate doing water changes and I have heard good things about sulfer denitrification. Has anyone here had success with it in a big tank? Will post pictures as the equipment comes rolling in.
