I decided to brace the top left and righthand side of the tank, it will help hold the corners and also allow me to use powerheads rated for 1/2'' tank thickness. I cut slots in the brace to slip a 3/8'' piece of acrylic thru it to hold the powerhead. One on each front corner.
Cut the teeth for the overflow on the tablesaw and glued in the black out wall between the DT and fuge
I want to keep as much light out of the DT as possible. The light in the fuge will be on at nite. I thought I better cover the corners on this side of the tank. I cut the strips for the corners with bevels on both edges. It gives a more finished look.
All the black acrylic had been sanded with 800 grit to take the gloss off.
One corner in place.
I dont want to hear a waterfall from the return chamber to the DT, so I built a trough that will extend down into the DT water line.
I glued the clip on brackets to the skimmer overflow and added a 2'' half circle to the bottom of it to hold a powerhead. (again that 1/2'' magnet thing)
You can see the placement of the closed loop return for bottom flow
Next up a water leak/flow test.
