cigars I saw that video and I do think I will try that first, thanks! flukekiller If that doesn't work then I will try the marine epoxy. The tank isn't fully set up yet so it won't be a problem to have a dry line.
The method from the video seems to have worked for me. No leaks so far...knock on wood. Now I have another problem, but I'll make another thread about that when I figure out a couple things. Thanks everyone!
