This Rube Goldberg assembly was the result of having a bunch of colored pvc remnants from earlier builds. The Nuvo's drain drilling pattern complicated the layout. Relieved to report that the leak test just passed with flying colors. Final assembly includes 3 Red Sea ReefLeds, Trigger Systems Platinum 34, Maxspect SK 400 skimmer, Syncra SDC 9.0, and 2 Jebao SCP{ 150M crossflows. Next step: aquascaping.
