Bubbles on water surface

[HalfMoon B]

Any idea what's causing this?
Running a 29 gal, with an hob filter, all water readings are norm (0 ammo, 0 trites, 15 ppm trates)
The tank is planted, now new fish or invert or mini cycles, and no water change since Saturday.
At a loss to explain this... The bubbles aren't soapy/foamy, and disperse after a few minutes, but it seems like my filter's water agitation just keeps fueling more bubbles.
Should I be worried about this?

That happens on my tank too. It's just the result of surface agitation. You're fine! if you're worried, just raise the water level a bit. It should go down.

Could just be excessive evaporation. I have left my feeding lid open the past few days for added gas exchange. Good to know!!

That's pretty much it lol. The more evaporation, the higher the surface agitation, so they're basically the same thing! Lol.
