Soapy like film on my water surface (cycling tank )?

Soapy like film on my water surface (cycling tank )
Ammonia > 0.25 nitrite = 1 nitrate 10

it was like thin film and today it converted to something like soapy tiny solid particles ( like scratched solid soap powder )
Is that normal ?

 

it is trapped protiens , they are trapped by surface tension

you need to increase your water movement at top of tank - create ripples (waves in my case)

that will stop them forming at water surface
and if and when you get a skimmer, the skimmer would help to remove them

you can get rid of them by placing a dry paper towel gently on water surface and then carefully peel it off, the protiens / scum, will stick to the paper towel

2 or 3 goes at that should remove it all
then you increase water movement at the surface and voila - they never come back

 

I never realized what that film was either. I assume it is the same for fresh water as well.
