I guess with that plastic and tacked on wooden slats your hoping to prove either way where the leak is coming from, provided the plastic which I am assuming is sealed with sealer on both sides, will hold out the water temporarily for this test. I certainly am hoping so and that any solution decided upon works well and permanently.:grinyes:
By the way, what is that thing below inside the tank that looks like the corner of a coffee table with a cup holder built in
, not an underwater coffee table?
