I have a 55 gallon display and a 30 gallon sump setup. And I just got a new 100 gallon display and would like to tie everything topgether into one system and since I have two cabinets now I think I may get an extra sump to free up some room for my skimmer or refugium so it brought up the question Is it better to have the refugium before or after your skimmer section? I have seen both done on succesfull tanks and can see pros and cons for both. Just wanted others inputs.
