Oily Substance

[AlyG]

I just started using mysis shrimp yesterday & I noticed an oily substance filming on the top of the water. Is this from the shrimp, if not, what could it be?

It`s a protein sheen. A protein skimmer will help. Also a PH pointed slightly to the surface will help. I never have a problem because I have 2 overflows that the water travels down to my refugium.

I agree with Mike.

2 words, protein skimmer

I agree with Melosu and other than being considered aesthetically unpleasing to the eye, it won't negatively impact your aquarium. I'd go the powerhead route for surface agitation before spending a lot of money on a skimmer that you may not need .
