I was thinking about a mated pair of Allard clowns to start along with a mixture of hard and soft corals (probably Acropora, Xenia, Clove, etc.) and a Bubble Tip Anemone. Obviously, this will be done over time as my tank matures. The setup will be a 29g with IceCap 250W MH 20K, 24" CPR Refugium, custom sump with 150 Won Bros heater, Remora Pro w/Mag 3, Iwaki 30rlt and SCWD. Unfortunately, my tank has no prefilter so I'll be looking to build a pre-filter with stand pipe. This is where I am at as of today. I need to drill the tank for the pre-filter and dual returns. I was just curious how other people decided to do their plumbing and what gotchas I should expect moving forward...
