I have a 75g display and a 29g Sump. In my sump I have a protein skimmer, refugium, bubble trap, and return pump. For intake I have two 1-1/2" PVC into protein skimmer section going through filter socks. One is full siphon and one is half siphon (bean animal setup). There is definitely no way to add another chamber or anything so I'm looking for suggestions on how I can add a few things... I'm assuming somewhere in the plumbing I'll have to tee off but I want to see if anyone has any other suggestions or can suggest where to tee off.. Basically I'm looking to add a Carbon Reactor, GFO Reactor and UV sterilizer.
