I was looking into finally getting my 240g tank up and running and I ran into an issue with predrilled holes. I think I am leaning toward sealing those and drilling new holes, but i would also need to buy new bulkheads. I found a few websites selling uniseals and these almost seem easier to me to use rather then a bulkhead because i won't need to worry about threading the holes.
Has anyone used these? How to they work? More importantly, how do they work on a large tank?

if you mean pressure of the pvc against the seal and the seal against the tank I understand. As long as you use a hole saw and drill the proper size hole they seal great, damn near impossilbe to remove the pipe once in place. But like I said, on the bottom of the tank I'd be afraid the water pressure would push it out, proabably wouldn't happen; but still, I'd do bulkheads on the bottom of a tank but I wouldn't hesitate to use uniseal on the side.
