Been in the hobby for a little while and looking to upgrade to a large tank that will be SPS dominant. Several years ago I started with a 40g breeder, then went to a 90 bow front, and recently tore down my 220 because I had to move so now i'm taking advantage of the new house and the wife let me build a fish room. I've done a ton of research, and settled on A.G.E for the tank (84x36x24H). The tank with be 3 sides low iron, with 1" pvc bottom. I like higher stands, so they are building me a 40" high steel stand made by 2 x 2 x 1/4 inch thick walls. As for overflow I opted to go with a single 20" synergy reef overflow. As for sump i'm going with a custom Bashsea that will measure 72x24x20H (I always love running large sumps) I'm still debating on if I should just use a large rubbermaid trough or another tank for a fuge. I wont be happy unless its atleast 50 gallons. As for equipment - Skimmer - Bubble King Deluxe 250 (internal) Return Pump - Abyzz A200 RO/DI - 6 stage BRS 150gph ATO - Tunze Osmolator Controller - Apex (with extra power bar) LED's - (4) Ecotech XR30 pro (maybe some T5's if on budget) Flow - (2) MP40's (2) Tunze steams Calcium Reactor - Geo's CR624 Carbon Reactor - TBD (probably Geo's or Bashsea) Mixing Station - (2) 75 Gallon containers from e-plastics and Pan World 50PX-X Live Rock - 250 lbs of pukani I probably missed a couple things off the top of my head, but you get the idea Looking forward to discussing my build, and gaining some knowledge. Here are some pics of the electrial work I did today. Deff sucked running wires in the attic in the Florida heat. I will be running 3 dedicated 20A circuits to the fish room/tank, and Running a Cat6 wire for the Apex.
