Seems that I cannot place a new post into the classified, so I thought I would mention here.
I have an AquaticLife 115 Protein Skimmer that I bought new and does not fit in my IM 20g tank. Unfortunately since it has touched water, I cannot return it. Paid $50, was in the water for about 5-10 minutes, willing to part for best offer. I know it's not much for most of the members here, since it's only good for 30 gallons, but I thought I would put it out there...
