I am looking for a external refugium that would be fed by a pump from my Synergy Sump and flow out back into return section or my sump. I have already asked Synergy if they could do it. They wont, not sure why as it wouldn't be any different then a sump. It would actually be easier and I could keep the same design. I'm pretty sure it will have to be custom due to the dimensions i'm working with. Does anyone have any recommendations on who i should get to build it? I am looking to put it next to the sump on the right in the picture below. I want the fuge to be taller and have a drain on the side so i can pipe it back to the return section.
