300 Gallon Plywood Tank Leaking - Best way to seal? Pics!

[ITHURTZ]

Did she do 50-70% water changes to see if the window slipped or popped? On my tank I drain the water below my little acrylic window. Mine I am sure would leak eventually if I did that. I have yet to test the peel ability with acrylic and liner with marine 5200, or liner to liner with 5200..

I have some 5200 left over, so I am glueing liner to liner, Ill show the results in a week when its cured haha.

The way that she had it set up it really wouldn't matter how much of a waterchange was done... the presure on the gasket was created with a extra piece of wood inside the tank... Let me see if i can find it


HA!!! After 25 mins I found it

here it is

Basically the same thing, instead of direct bolting to the tank, she sandwiched it in between. Either way the plexi wouldnt fall out. I wouldnt trust just plexi on pond liner with a sealant. Well Ill have to test that out to, Ill make myself a wood frame, line it with liner and put on a peice of plexi wait one week, and hit it with a hammer.
