Here is my 120g Reef Tank. This tank is just over a year old, it was an upgrade from 55g. I have been in the hobby for about four years now. The cabinet is hand built because I could not find a cabinet that could hold all of the sumps and equipment without having a seperate room.
Tank: 120 AGA with Corner overflows
Cabinet: Custom 6'x6'x30"
Lighting: 2x400w 20k XM; 4xActinic VHO (It is a little blue, I will probably swap out a pair of the actinics for a whiter pair, or I may go back to 10k Aqualines)
Filtration: A little carbon and a Life Reef VS24 Skimmer.
Sump: An Life Reef LF75 Sump holds my probes, float switch, and Carbon. Custom Built Refugium.
Main Pump: Dolphin Ampmaster 2100
Controller: Octopuss 3000
Chiller: Custom Sea Life 1/5hp
Calcium Reactor: Life Reef
RO/DI controlled by float switch controls evaporation
Suppliments: Kent Tech CB A&B, Tech M, Tech I, Iron Supplement
Light Cycle: MH 10h, Actinics 12H, Refuge Reverse 12h
