What is your tank rim size? The reason I'm selling is:
1. Doesn't hang well on my 2 inch Eurobrace rim. Outlet hangs over fine but inlet ( with water pump ) can't fit over well because the bracket doesn't fit.
2. The water pump is huge! May look big in your 24g.
It should hang over if your tank has standard rim. You can check out the specs on Current USA website under ( Fisson Power Skimmer )
