So my tanks old enough that the trim is falling off the bottom I have no idea if the bottom was already chipped under the trim or if its from moving my tank a couple years ago. I had a mini crash from setting up a new sump and found this in the back corner of my tank while looking for problems. Forgive the cobwebs etc haven't looked at the back against the wall in a long time. It looks like water staining by the chip but theres no moisture its dry and no moisture under the stand or in the 2x6 supports. At first I thought the pane was installed/settled off level but its a chip going a quarter of an inch in. Glass is 3/4 inch thick. So tear down or patch with silicone? Thoughts?
Tank was running as a freshwater for 3 years before being torn down and moved and has been sitting there just over a year
