Tunze® Comline® DOC Skimmer $58 (half off)
up to 37 gal

Warning: if it is like the recent posting and reposting by DFS for Tunze Osmolator for 50% off that was actually not available, then you will not get this skimmer. However, if you would like one, I would try for it just in case it is an actual deal.
I have this skimmer on my 22g frag tank because it fits in the tiny overflow box and does a pretty good job.
(too bad it doesn't remove monti eating nudibranchs)
