Skimmy
SKIM FU
yeah, that's what ive heard about h & s as well, i was looking at a used one but then was talked into buying the grotech jojo had for sale from a friend who owned one. if it didnt kick butt with it's normal post impellar venturi so well i'd put more thought into turning it into a needlewheel skimmer or better yet the new threadwheel, but i set this thing up and was blown away with it's ability to produce nice foam, so im just going to leave it for now.
