Looks like normal green algae to me. Just because the algae captures tiny air bubbles in it doesn’t make it bubble algae. Bubble algae is very distinct in that it IS the bubble, it does not have air bubbles trapped in it. That also doesn’t look like hair algae to me.
That looks like work for a standard cleanup crew. Snails and hermit crabs. Scale your cleanup crew according to how much or how little algae you have. For example, if you see algae start to increase with your current cleanup crew, then add more hermits/snails/etc. This isn’t something you would use additives for. You could always manually remove it yourself if it bothers you that much.
So no, nothing to worry about, it’s normal growth.
