Now it was time to make sense of the plumbing in the tank... Keeping with my original plans I went with an Oceans Motions 4-way Closed Loop powered by a Reeflo Dart. The intake is halfway up the back panel of glass, and the outputs exit at mirrored points on either side of the back pane, and the others close to the front corners on either side. I lost a few braincells gluing all this stuff together.
Closed loop plumbing completed:
There were serious delays in getting the remainder of the equipment I had ordered so I took November and December off and drank beer and snowboarded instead.
