More Surface Agitation?

I've been cycling my tank for a couple of weeks now and I seem to be battling the white surface film. It was kinda thick at first so I've been playing with the output tube of my canister filter to try to stir it up a bit. The tube only goes about half way across the tank so it seems to be just moving the film over to the other side and then returns back in front of the output tube even though it has gotten thinner. Should I get an air stone? Powerhead? Try mounting the output tube to the side of the tank? Maybe my filter is too small? What do you guys think?

I recently trimmed up some hornwort and let it float on top to see if it would break it up some but it doesnt seem to work that well

Fish in or fishless cycling? Were your hands clean when setting up the tank (no soap or lotions)? What kind of filter are you using?

Fishless. I'm fairly certain my hands were clean aside from the dirt under my nails from putting the dirt in. Its not a surfacant if that's what you're aiming for. It appeared probably 3 or 4 days after the tank was up and running. My filter is a Sunsun 402B
What are you using as your ammonia source?

Ace Hardware 10% solution. Not my first tank. Just my first planted tank :grin2:
Then I'm not sure. There are no organics in the tank yet, so I'm not sure what the film is. Just trying to figure out what you put into the water is all. Plants don't have any thing on them that would contribute. If you have fish, they would be a source of the film, but you're doing a fishless cycle. If you were using food as your ammonia source, that could also be a source of the film. That's why I was asking. If you don't use Purigien, I would highly suggest it. It does an extremely good job of keeping the water clean. You'll want surface agitation for O2 transfer anyway, but that really doesn't get rid of the film.

Do you have driftwood in the tank?
I've had this on both my tanks. Ive chalked it up to being driftwood or new cycling tank syndrome. It seems to go away after a few weeks. I also use the chemi pure elite bag in one filter to help keep the clarity.

I do have driftwood in it. Its the tank in my avatar.

I'm starting to think this is most likely the case. It seems to be getting thinner and thinner by the day.
