I picked up an acrylic tank cheap online yesterday (see pic). It's 6 foot x 12 inches x 12 inches. When I went to fill it the front maybe 6 inches at the seam leaks. What would be the best way to fix it? Is it worth fixing? I'd prefer to fix it, but if it's too expensive, too much work to save I'd rather not bother with it. I've never really used acrylic tanks before.
