Unknown build up of something on surface

[kiwis]

Just around my return pump and overflow, there seems to be a very fine layer, almost transparent. I can only notice it due to the water being so still whereas other water is moving.

Any ideas why this would be.

Clear slime ?
This builds up in low flow areas and can float on top of the water and overflow teeth, or just about anywhere there is no turbulence

Anything to worry about or suck it up when I go a water change in a couple of days?

is it all over the surface of the water in the top of the tank ?

Nope "Just around my return pump and overflow"

Just stir it up or brush it off
