filtration

Greetings, I am currently starting a 120 gallon (48x24x24) build. I already have 200 watts of LED lights and now I am working on the filtration. I am going to have a refugium filled with live rock rubble and either an ATS or Chaeto reactor. Which is better?

Hi everyone, I just wanted to get your opinions on this stocking list for my 92 gallon aquarium. I want to make sure I am not overstocking and I like getting peoples' opinions on things like this :) It's a corner with about 90-100 lbs of live rock, a sump with bio-ball filtration and an Octopus...
