Seen it, and really thought longingly about it, our skimmer could really use an upgrade. Went so far as to look long and hard at what I could get away with fragging without Angel beating me over. Still thinking about it though.

But I just need to increase the return rate for my planted display tank/refuge, a Mag7 with only 3-4' head would be way too much, I'd have to throttle it back to over half, no sense beating up the pump like that.
