Foam floating around edges of Aquarium.

So I'm wondering if anybody knows why I have white foam bubbles floating around the edges of my aquarium. No I didn't use anything with soaps or detergents.
It's a fairly high light tank I think... 17.6 gallon with 2 24watt T5HO. C02 system hasn't arrived yet, just using that Tropica 60 bell thing for now. Lots of plants, pogostemon erectus, monte carlo carpet, Murdannia keisak, Hydrocotyle tripartita, alternanthera reineckii mini. I have 3 pea puffers, a few ghost shrimp, 2 amano shrimp, malaysian trumpets snail and pond snails. The snails are obviously for the puffers to eat.
PH 6.8 GH 4, KH 0. And my Nitrates stay at about 5 ppm without adding any nitrogen. I do weekly water changes that are about 4 gallons.

It's a very common protein film and can also be residue from fertilizers. I get it when my floaters overgrow the tank and reduce water movement enough.

You just need to create more surface agitation or add a surface skimmer, and it will go away really fast
