Here is our 90g tank on a 120 stand( to make room for the 40 breeder and the GIANT skimmer) canopy with coralife 36" T5 4 bulb fixture. It uses a cpr overflow. The sump is split into 2 halves. 1st half has bubble trap, 10w UV, skimmer and 20lbs of live ruble. 2nd half(split by a washable filter wall) has cheato, some red macro, carbon and nitrate rock reactors and a small powerhead to spin the cheato. Pump box on the right side houses heater and all of the pumps. 2 Korlia 4's in the tank push a ton of flow for the following happy fish( yes, overstocked, but GIANT skimmer and weekly 30g waterchanges make it work). Lionfish, Dogface puffer, Porcupine puffer, Huma trigger, Undjulated trigger, Yellow eyed Kole tang, Koran angle, Harliquin tusk and a cleaner wrasse that is the funniest fish to watch. Hope you enjoy.
