The water will be pumped into a large diameter PVC pipe above the tank rack which will serve as a gutter, bringing the waste water through some spiral tubing leading outside and into my pond.
I can get Aquatop NP-306 496GPH pumps for about $17 each so they can act as my powered drains for each tank. I also have other pumps at my disposal if needed, though at a bit higher cost.
