i agree everyone seems to be on the fence about this little product... i have a friend that i work with that loves it but i hear of other who curse it.....like every other aspect of this hobby i suppose!
good luck

I have a Seaclone 100. It used to be on a 29 gal. I liked it. I don't know how it would work on a larger tank. Adjust it so the little "tornado" is well defined & it should do OK. It took a few days to settle in before it produced nice dark gunk (technical term). It did take some ongoing adjustment.
i kept two SeaClone 100s in the past, and i liked both very much. They did a good job of cleaning out the water. I had to empty them almost daily they were taking out so much junk.
I'd say get your venturi going well and it might spit microbubbles til it breaks in (about a week) and then you should start getting quite a bit of skimate in it. That's how mine was anyway.
