Once a tank gets passed a certain size I am not comfortable resealing unless all the panes of glass are disassembled cleaned of old silicone and then put back together. I never have been a fan of resealing tanks in the fashion you are doing. Many do it this way because well it is easy.
Probably fine but 90 gallons of water on my floor isn't worth the risk. The time to clean up, dry the carpet, replace damaged floor, etc... well it would be far cheaper and quicker to just buy a new tank.
