Well after learning so much from having been a part of R2R and a local Reefing club I have finally decided to take on a full SPS 75 gallon rimless tank. So far for my equipment goes. I have a WM 161 skimmer (Skimz 161), a ecosystem sump 36x15.5x18, a dc12000 pump, a brs dual reactor, 2 drews dosers and 2 mp40's. Then I am using my Neptune Apex with 2 eb8 and 1 eb4 to control everything. I just started the build on my stand. Still need to make the doors. For lighting I'm thinking of 6 or 8 bulb ATI fixture. As my tank dimensions are 48x18x20.
