The 140 has a SeaQuest rated for 75 plus gallons... moded to draininto the sewer, not lookin back - and then a wet cup mod to rinse away the krud....it's the waste from my ro system... venturi style...

I've changed it so much it dosen't look like the box flap it came with...
The 30 soon to be 75 has a turbo floator on it, with the needle wheel.
And the 240 gallon wall has the Nautilus TE from Kent.
I'm fairly happy with all, but if I could plumb anything together, would love to replace them all with a diy monstrosity... you know, the mark of a true Jedi Master is to craft ones own skimmer...and have it be impressive.
