do you have any cleanup crew? a few trochus snails will take care of that kind of algae fairly quickly. Since your tank is young, then the next type of algae starts to grow. It'll settle down in time. Short answer, yes, pick up a few snails
It's a new tank. Pretty normal for it to go through stages while the tank matures. Turbo/astrea snails are great algae eaters, but I suspect it will gradually fade away as the tank matures, given that the water quality remains good.
