Should I be worried or not?

Should I be worried about these air bubbles in the silicone at the bottom of my tank. It was a custom built tank about 8 - 9 months a go.

White lights pics please. Blue makes most attempts at identifying nearly impossible

This is a better pic, try with that if your able to zoom. It takes a bit of effort to change to whites the lights are high up and they are kessils without a dongle haha. If that pics no better I will change them to white though.

Looks like bubbles that are not part of the actual seam? Where the glass meets is the area that provides structure. Any run off above or below doesn't provide support. That being said it's something I would keep my eye on. If a brand new tank I would consider warranty.
