Smokey layer on top

[albino]

I have just setup a 2ft planted tank 2 week plus. I always saw a layer smokey layer on top of the water. I try to scope it out but it still there. I don't think is oil. Just changed 30% water on Saturday since setup 2 weeks ago.

I am using :-
1) Lapis Sand
2) JBJ Substrate Nutrient
3) Canister Filter
4) Driftwood x2
5) DIY CO2 with diffuser ( sugar, soda, yeast & water)
6) DIY Fan x2
7) Java Moss, HC, etc (not much plants now)
No fishes.
9) 55w PL light

Any kind advise ?

Thanks in advance...

Cheers...

You need to get a surface skimmer.

thanks for all the kind advise.

will try to get platy or mollies but have asked around Y618 and polyart, seem like mollies is not very popular nowaday. I am looking for those normal type of black mollies for my other tank. Anyone come across it ?

Thanks...
