Layer of plankton??

i have a thin layer across the top of my water. to me it looks like plankton or some type of small algae. i do not see it in the filter portion of the tank, only in the main part. the tanks been running for about 3 months. anyone know what this is and/or how to get rid of it...protien skimmer??

 

How is the agitation on the surface of the water.
Try to point a power head so it ripples the surface.
That layer could be reducing the amount the tank is able to off gas and could cause a reduction of O2 in the water

Most things nasty are destined to end up on the surface of your water. Protein skimmers take advantage of this and operate on the exact same principle but with a LOT more surface area. It's not a good idea to leave these things in your tank and I would definately recommend a protein skimmer.

I'm not going to discuss hydrophobicity or hydrophyllicity as this article can explain it a lot better than I can.

i have the same trouble, and it started right after i stopped using my skimmer. i have to save up some cash for the one i want. but now knowing others are seeing this im sure its the cause.
