Hello Everyone!

I am new to the community and I just inherited a 90g reef tank setup (lights, sump, drilled tank, ATO reservoir and stand) from a good friend of mine. LONG story short, my friend decided the seals on his tank were questionable so he purchased a new tank and gave me most of his old setup. The corraline algae appeared to be growing into/under the seals (pictures). He did purchase the tank brand new about 3 or 4 years ago. Tank is dated October 2019.

Currently, the tank is empty and in need of a good cleaning as it will not be setup until I get a bigger house (hopefully in the next couple of months). So I have time to assess the situation without worrying about fish, corals, etc. I found some similar posts but wanted to go ahead and dive in with my first post and see if anyone could give some guidance on whether or not he seals are going to be a big problem down the road or if resealing would be the best option. The 'nuclear' option would be buying a new tank.

Two of the four pictures are when the tank was setup and running and the others have arrows pointing out what I'm asking about specifically.

Any advice or direction is greatly appreciated!

It looks ok to me, no serious bubbles going on. I don’t know that coralline damages silicone, others may have experience
 
You can cut out the old silicon and then install a fresh bead through out the tank. I know it sounds like a daunting task, but if you are going to do it, do it right.

I've resealed dozens of tanks. In you case, there is no need to disassemble and reassemble the tank. Just cut the existing silicon down to the glass, clean with white vinegar and reseal.
