Hey I was out tank hunting today, after last month having found a 55g along with some smaller tanks, and I came across a pretty big octagon tank, im thinking its 30-50 gallons ( confirm/deny?) . Problem is it has no frames, which im sure actually dont help much in support as they do in aesthetics. Does anyone knwo where i can find octagon frames? If neccesary, whats the process for resealing these thanks? I've done resealing on big rectangles but never anything else.
