I have a 55 gallon tank available, with old plastic tops, for free. It apparently leaks, but the glass looks intact, so I think it simply needs to be resealed. A neighbor wanted it out of her basement.
It's available for pickup in Northwest DC, just inside the line with downtown Silver Spring. Alternatively, I can bring it to the November 2 meeting, if you make a $10 donation to PVAS.
Taken!
