Yah, thats about the worst skimmer out there. I know, i bought one six or seven years ago when i started out in this hobby. I think most hobbiests go for the cheapest items needed in this at first, because they really don't understand the money thats involved. These skimmers have been junk for at least six years(that i know of), why are they still selling them... cuz the inexprienced people will buy them. (sucks)
You could put the skimmer up for sale here, but i would cut your losses and use the power head in your tank or to mix new salt water with(like i did).
I had a BakPak for about a year and really wasn't impressed with it, i than bought a Prizm. Lots of people hate prizms, but for me it works great on my 38g! I did a few very simple mods to it and now i can run it wide open and it collects some good sludge. I say, get a prizm ($70) or....if you can swing it, lots of people like the Remora Urchin, witch will run $150 or so. Seems like the Urchin is top of the line for tanks 75g and under. If you are on a tighter budget, get the Prizm. JMO.
