Foam at the top of aquarium

[Hardesty2]

Hey y'all i just set up this 20 gallon this morning. there's a little bit of foam on the side of the top of water, is that anything i need to be worried about? thank you!

Nothing to worry about, but it does tell me you need more flow at the surface. What are you currently using for flow?
