(Sorry for stealing from OP!)
That is a protein scum, and yes, I have it, more in one tank than the other two. I used to use surface skimmers on my canister filters, they pulled it off without causing disturbance to the water surface, but unfortunately fish kept getting sucked in, and as I have so many small fish, not to mention regular spawning in all tanks, I took them off rather than fiddling around with screens.

Now I just use the Python during the weekly water change inverted from underwater to pull most of this off. A bit of effort, but not too much. It is not really a problem, but built up it does reduce the exchange of gas, or so I have been led to believe.

In my Amazonian setups i seldom have this, probably because the filters do create ever so little surface movement. In the SE Asian tank, where it is the worst and quite thick, the floating plants prevent gentle surface water movement. But as I have spawning Chocolate Gourami and Pygmy Sparkling Gourami in there, the plants are staying put.

Which part? You explained it so well in your following post. But what I meant by airstones at night...I know a few people who run airstones at night (a few people on this forum mentioned they do as well) but only at night, because that's when the fish seem to need more oxygen because plants cease producing it when photosynthesis stops. For me, I became concerned about oxygen in the evening when I had a mishap in my tank one day, that evening found all fish and shrimp in the top inch of the tank, gasping, fixed the problem, and have been watching that tank ever since and fiddling with the surface disturbance to ensure that there is in fact enough gaseous exchange to provide enough oxygen day and night. The history: http://www.tropicalfishkeeping.com/f...rs-help-39319/

I actually do believe that this mishap was due to formaldahyde poisoning from the pantyhose (formaldahyde binds to O2 and can be found on new clothing...it also kills bb, and my tank had a mini-cycle for the week following this mishap).

Your first post had this line:

i also have the fish gasping thing when i have no surface disturbance so i will be following your thread.

and that was what I was asking about, thinking this was a regular daily thing. Now you've explained it isn't so not an issue. Fish gasping every day or every night should never occur "normally," and that was what bothered me. B.
