Last year I got a 40 breeder. Unfortunately after a few months of it running, there was a leak. I believe there was just too much gravel and had a piece of driftwood that was probably a little to big. I think the silicone separated from the glass somewhere near the bottom, to my knowledge there is no cracks in the actual glass. I don't have the skills or confidence to repair it myself. It would make a great terrarium if you don't want to reseal it.
I am in Woodbridge, right off Route 1. I'm not asking for any money for it, but if you have a bunch of pond snails, I'll take as many as you could spare.
