Thanks. The problem was Pond Armor. There is apparently a tiny bit of movement when I climb in and out of the thing, and this caused stress cracks between pieces of wood. I spent a long time trying to get the epoxy to work, including siliconing the stress points, but its too brittle. Finally, I switched to Sanitred and it worked right the first time. It was up for a while before it leaked as I try to avoid climbing into it. The Sanitred is immune to any flexing.mr.reef24;3315291; said:great DIY tank how often did it leak before and where at in the setup?
