I realize this is a little bit of an unorthodox set up, but here goes.
This drawing is not to scale at all, but here's the idea I came up with for my 90 gallon Tang community. The tank on the left is a 20 long, and the tank on the right is a 5.5 gallon. The idea is to have the 5.5 function as a freshwater refugium, but also be able to be closed off from the circulation loop of the rest of the tank and be used as a QT/hospital tank. The light bult is for the upflow algae screen in the right side of the 20 gallon. I'll have gate valves in all the places where I'll need to shut off flow for the 5.5, as well as for maintenance purposes, but I didn't put them in this sketch. There's also going to be some sort of floss or sponge jammed between the left-most baffles to prevent any solid waste from getting into my wet/dry filter. I also didn't draw the drain I plan to put in now so that the system can later be changed to a continuous drip system. I figured the drain would go in the pump chamber a little higher than the pump itself? That would be my first foray into that, so I'm 100% on how to do that. Does anyone have any feedback or suggestions before I start work on this thing this weekend?
