Hey all,
I purchased a 90g glass off craigslist for a great price and what do I do when off loading it... Crack the bottom. Thoughts on repairing with a piece of 3/8" glass over the top of the cracked 1/2" bottom?
I wouldn't do it. You are far better off removing the broken piece and sealing it back in correctly. A 90 probably has 1/4" glass but could be 3/8" depending on manufacturer.
Not if done correctly. The issue is, many skimp on the silicone and only do the seam. To properly seal a tank, you have to lay a bead where two panels join, clamp, then lay a seam bead.
