Thanks again

I understand Kevin. I am just concerned, and am urging you to reconsider trying to fix this tank, but I won't comment anymore.

windshields dont have 300 gallons of water pressure on them causing them to bow either. I think I would bemuch more confident in the tank if it had a new back panel...

I would suggest you error on the side of caution. I think you should just cut through the sylicone and have new pieces cut and re-installed. I'd hate to see it come back to haunt you later.

I'm not sure that your overflow will have less pressure as the pressure at a given depth is independent of direction -- it is the same in all directions.
I have a large tank myself and just knowing how much time and effort went into the tank as far as livestock, corals, liverock etc, I would replace any glass that might have had it's integrity compromised. Everyone here has seen what a couple of spilled gallons can do let alone hundreds. Your investment will end up being in the thousands of dollars by the time your done. Don't cheap out just to save a couple of bucks

I have been doing a lot of thinking about fixing this 330g and thought I would just see how much a new back piece would cost. So I called Mitch at Bow Valley Aquariums and he said it was a very slow day due to the cold and if I wanted the back today he would give me a good deal. While I was already there I picked up a front for my 78g cube. Now I just have to wait for the weather to warm up and I have some cutting to do. Mitch at Bow Valley was very helpful and informative. He told me the skinny on cutting the back panel off and how to properly silicone the back piece on and was able to get me some silicone and tape. Thanks all for your input and I will keep everyone informed on my progress.

Well I know when I took my 280 gal apart it was 5/8" glass and with 2 people its alot easier wit 2 . when I was stripping the silicone off I had my self actually pulling hard on the glass and the other guy was cutting it it actually went really smooth too. from total time it was like 45-60 mins from the time we started to the time we ended..


good luck,

good luck,

When I did have to cut glass off, an expanding clamp helped alot along with this strategy of pulling and cutting.
