I have a JBJ 65 now and as you can see in the pictures Of how I’m going to set it up I have a couple of questions. What would be the best place to put the pump and the return? In the third place where my fingers playing I will be setting up a refugium so no where there and As you can see on the far right I have a skimmer. The middle section is the pumps. Would it be best if I have the pump in the actual tank and the return going into one of these places in the back? I would’ve bought a different The reactor for my tank but it’s what I have. Thank you
