Eductor/Penductor Efficiency and Performance Data?

[rockskimmerflow]

Flow update: The 1oopx-x is just too strong for even a 7' raceway when it's running at full throttle. I have about 500gph bleeding off it through a manifold that drives the GFO and UV sterilizer and yet the in tank gyre is proving too strong unless I throttle back the main valve on the pump. I started literally stripping tissue off the tips of some SPS that are on the far end of the gyre from the eductor input once I let the pump run at full open (still while feeding the UV and GFO). Throttled it back down and the pieces are recovering. Really can't exaggerate how impressive the flow multiplication the eductor creates is. I've even started using some in applicable client builds and am having success with no powerheads, cords, or any moving parts in the tank. I prefer gyre flow in general so the fact that this is a feasible means of achieving in display tanks is making me wish I'd given eductors a serious try a long time ago.

They really do work. Idk how they went out of popularity
