Top of water is weird?

Question

The top of my fish tank is covered in a thicker cloudier layer. Whenever I put food in it sepaerates and some parts turn clear.

It is sort of hard to explain, but its like a thin sheet of something is sitting on the water and it breaks whenever food is dropped in

I just did a water change yesterday, and it has been doing this for awhile...an help?

Answer 1

That layer is caused by not enough filter movement in the water. Either turn up the filtration, add another filter.

The skin is like when you leave move on the counter, and it gets that nasty looking skin layer.
