Hi there just read through your build. I just went through all this on my 55 gallon reef tank. As long as you have enough flow, and a good skimmer, you do not need a HOB or canister filter. I just removed my HOB it was an emperor 400. I have a reef octopus bh-100 HOB skimmer that works great. I just got a sump built w/ a spare 10G tank I had. Check out my build it may help answer any questions you have. But they are correct. The most important thing you want to spend your money on is a skimmer and lighting.
