Old 35g tank - will silicone dry out?

[attheworld]

Recently I've received a used hexagonal 35g tank. I think it's a custom tank, considering the odd volume/shape, simple stand design, and in fact a DIY lid. The owner who had it previously bought it from another person, but they only were able to set it up for a few months before they had to move households and sell the 35g.

It looks like the seams have been resealed (but the tank not rebuilt?), and I'm wondering if there would be any negative effects if the tank were to sit completely dry for a few months. Some of the silicone is peeling at the bottom, not directly on the seam though. There is a lot of silicone inside and a little bit on the outside corners. I know absolutely nothing about silicone, building and sealing tanks, but I think this tank may have been a DIY project and it's better to be safe than sorry.

I had a hex tank this size given to me by a friend, and they were still being sold i think it was petsmart i used to see them at, at the time.

Best thing to do would be to put water in it somewhere that you don't care if it gets wet, and do a leak check.

It's possible then that the silicone is maybe not the best quality if it's from petsmart

I did a 4-5 hour leak check with the filter and heater running in the tank, filled up all the way to the top. It didn't leak at any point, all water around it was spilled by me.
