Bubble build up

What’s the best way to prevent and get rid of these bubbles from building up?!

Some fish, such as bettas, make their own bubbles. I'm not an expert on bubble nests, but that doesn't seem to be the case here.

Running a power head close to the surface might help if you dislike the bubbles that much, but not all fish appreciate a hard current.

If you're running anything with an airstone that would be an obvious culprit.

I just went through that. Culprit was over feeding I am sure of it. Its caused by excess protein build up. Solution, few extra water changes and I added Purigen to filter, bubbles gone.
