I created this as a small (approx 2gal) refugium for my JBJ 65 gallon AIO flat panel tank. It's designed to fit the center 8-3/8 in sump compartment. It sits atop the stock return pumps and the return lines go through the basket. The fuge is comprise of a printed top and bottom and a piece of 8x10 inch x 2mm clear plexiglass for the rear side. The rear plexiglass allows a grow light (I used a IM ChaetoMax) to be externally mounted on the back of the tank.

Note: I also decided replace the stock flexible lines with 1/2 in pvc tubes and fittings. This makes it easier to remove and replace the basket for adjustment and cleaning.
