I have a HOB skimmer for sale, rated for up to 120g. Company that makes it is now out of business so there is no customer service
Never dumps water on the floor (as long as you don't plug it in), easy to clean ( if you don't plug it in AND keep it covered in shrink wrap).
If you choose to ignore above advice the skimmer is a plug and play type....plug it in and you have to play with it for hours
I'm up for offers, I paid $349 for this piece of junk
*edit* pump is needlewheel....a sicce pump I believe and it really does skim some thick nasty junk....when it's working properly
