Should I be worried by these bubbles?

I think they happened in a move. Just filled up the tank a red sea 250 and seems like they appeared the next day. I'm aware of the red sea issues just wasn't sure if this is a typical way they start and I should just cut my losses / avoid a flood , or if this is not going to go anywhere. Please see attached pics

Welcome to Reef2Reef!

From the pics you show, I think it looks fine. The silicon up near the sand looks like it's in good shape.

However, it looks like this may be a Red Sea tank, and if so, those tanks seem to have a higher rate of failure than other tanks. We tend to see it all too often, unfortunately, so I would exercise some cation here, and seek opinions other than mine.

My last thought, is your tank sitting perfectly on the stand? It looks a little off in the pics, at least to me.

Good luck with your tank!

Wipe the underside of the front glass pane. It looks like water or salt there.
Worth a try
