IME, it's not near as effective as transferring the clutch substrate on hatch night. When I tried it, I turned off all my pumps, and what I collected was paltry compared to the "flashlight and scoop/siphon" method. In all fairness, though, this is designed to be used on DTs and clutches with immovable substrates. I keep my DTs so overstocked, that I can't afford to leave the pumps off overnight for fear of o2 depletion. I think this would work awesome for the "frag tank with clowns" sort of system.
I got mine from Chad when he started building them.
