Old 90 gallon

[Pond9]

I have a older 90 gallon tank running no leaks and no center brace. It's 7/16" glass and it bows in the center 5/16" I've read mixed reviews and I'd like an opinion on it do I need to reseal it and put a frame with a center brace on top? Or what isn't broken don't fix? I've never resealed a tank and it has me quite nervous lol I'm hoping that it if fine the way it is but that diyking video of tank busting has me all paranoid lol. Here are the seals

Just to throw it out there, you don't need to reseal the whole tank to add a brace. I DO recommend adding a center brace.

what type of center brace would you recommend? Just replace the top frame with one with a center brace? Or something else?

replacing the trim can be a pain and might as well reseal while at it, if you do not care about looks can throw clamp on it. seals not look great but certainly not need to be resealed condition.
