So I have a 29 gallon tank I'm resealing. I started cutting out all the old silicone starting on the bottom. While making my way around, I noticed that the majority of the bottom panel isn't even attached to the side walls. The side walls all seem to be fine and secure to one another once removing the inside seal, but the bottom... Not so much. Can I remove and reinstall the bottom on this safely? The walls butt up against the bottom panel, they don't sit on top, so it would have to be slid inside.
