Yeah I guess I should have explained it a little better. I just drilled a hole in the 45' elbow that's below the ball valve on the pump return. The I heated it up and threaded in a fitting with some glue on it. Then I ran that to a ball valve, then down the side of the sump and out the bottom of the right side of the stand.
I turn off the water returning to the display and open up the small blue water change ball valve and the water drains out the bottom of the right side into my water change bucket
