Gill,
I think you just created a monster.
I was already looking at it and trying to figure out if I could drill it. So I could use a aqua-lifter as a power head.
Build a stand to hide that in, make a led that looks like a MH (at lest on the outside) and plum a skimmer in line. I wounder just how small I can make one.
Just what I needed, another project.
