Ive been doing some plumbing for my 92 gallon bowfront. ITs reef ready and has 1 overflow in the back thier are the 2 holes in the bottom of it one return, and one that leads to the sump. Ive done the plumbing throught the overflow but during one of my water tests i saw that one of the pipes was leaking. The way it is set up is their is a pipe that is in the overflow that partially sticks out throught the other side of the glass leading to the sump. Their is a ring type of think that you skrew up on the pipe so that it is tight to the glass and so that it wont leak. My concern is that i wont be able to skrew it tight enough. So back to my question is their a type of glue i could but on both ends of the pipe to make sure it doesnt leak.
Thanks,
Connor
