The bubbles most likely are co2 under the slick, with my current failings I've had a similar thing going on. I syphon from under it at water change time to remove it!
You could also raise your lights a bit to slow things down, or power them down a little as you probably have that function
Looks nice, any pics of the fish?
Cheerio

I expect they are CO2 bubbles as well. I had a few until I raised my lily pipe to create a big more agitation. Once I did that the surface was kept scum free (at least as a film) and the gas exchange increased.
Last photo looks ace mate!
The other advantage I find having air on is, it agitates the tank in a different way than the flow from the filter, thus moving "settled muck" into the water column to be taken out by the filter. I have a Boyo air curtain running along the back of the tank, slightly above substrate level, that I run from 10:45pm at night until 12pm (2 hours before CO2 on, 3 before light on).Antipofish said:ian_m said:Put an airstone and air pump on for say an hour or two when not lit and no CO2 and this kills the build up of oily film almost instantly.
Does this have the same affect as raising the filter outflow to create surface movement ? I can get an airstone I guess

A lot of flake foods that are high in protein leave an oily film on the surface (ie. Tetra Pro Colour)
