little bit of a desperate situation I have a very large plywood aquarium that I've been building for awhile finally get to filling it up and it leaks......through 4 layers of pond sealer.....through a layer of fiberglass(which goes almost 2 inches over the seams) . Around the screws that are 1 inch below the water(there is also liquid nails between the panels) coming out the bottom were the front panel meets the bottom panel and there's also a square patch i did at the back that's leaking as well but its got fiberglasss and sealer over it to(oddly enough the patch on the other sided that i did the same way isn't leaking...) , I'm just stumped at what to do. There are no visible leaks on the inside and I cant even comprehend how its leaking through all those layers without visible damage on the inside its hurting my head... front panel is 19mm marine ply 2100mm x 750mm
