I upgraded from a 6o gallon to a Deep Sea Aquatics drilled 105 gallon. I am still using the same 25 gallon sump, lights, skimmer, etc. I wanted a much more minimalist look. I reused most of my rock from my previous tank, only replacing the sand. Never experienced any recordable ammonia or nitrites fortunately. Everything survived living in garbage cans (30+ coral, 3 fish, and a bunch of inverts). Here is/was my old tank.......
And here is my new.........
