Sorry to hear that man..i feel for ya.
having spent a month building mine and quite a bit of money for a wooden box, i dont know what id do in your situation..
i told myself "if it leaks, ill order an acrylic one" but after $120.00 for 3 quarts of epoxy, and $60.00 worth of wood plus $150.00 for the glass, id sure hate to lose all that progress and money..
if its a seam, can i ask you some details on your construction?
i noticed you used fiberglass cloth in the corners... can i ask why you felt the need?
i used liquid nail to join mine,(the waterproof kind) and screwed it every 3".
the liquid nail oozed out nicely, and i wiped off the excess, leaving a pretty tight joint.
after the first epoxy coat, i really didnt see any line where the panels met, so i was confident it would hold. seeing yours leak has made me second guess myself. its pretty unnerving making an aquarium out of wood to begin with, so id really like to know the cause of the leak (as im sure you would as well) so i can reassure myself..lol
im waiting for my glass to arrive, and at this point, i guess its sink or swim since the epoxy is already on and dried.. (only 3 coats)
im guessing the fiberglass cloth with no resin, coated only with the epoxy is the culprit. maybe the cloth absorbed the epoxy and left voids?????
my biggest worry, is i made a mistake on the window opening and cut it 1/2" too big, leaving only 1 1/2" of gluing surface for the top of the glass... oh well *crosses fingers and hopes for the best" if not, keep me posted of any fix you found...lol i might need it...
the website i got my plans from only called for 3/4" plywood...i wish id have gone thicker
if you do decide to rebuild, and want to try a different type of epoxy .. heres what i used: nsp 120 blue 3 quart kit
