Help- layer of "stuff" on surface of new setup

[a&m '96]

I've got a new 65 gallon setup that's been cycling for almost two weeks. It seems to have a layer of VERY fine material (dust, detritus, etc) on the surface. I thought I did a good job rinsing my coral skeletons, gravel, etc- maybe not. Anyway, this stuff is being pushed to one side of the aquarium by the filter return and the powerhead, and is easily seen when looking up to the surface from below. It doesn't seem to bother the 3 damsels in the tank, and the water in the tank is otherwise perfectly clear. I was wondering if any of you have had this problem, and what you did about it. Will the filtration eventually get it? I have a Eheim cannister filter and I've got a red sea prizm skimmer coming in the mail. Thanks for your advice!!!

Hello, you need more surface breakers. We have them at each end of tank to stir up the water at the top so this doesnt happen. cya..fixit

fixit's right... you need something to agitate the surface of the water... I use an airstone, others use powerheads or hang-over style filters with no filter media.

Hopefully your red sea skimmer will let you adjust the depth at where it draws the water from. If so, you can set it just under the surface...instead of a few inches below, which then you will still have the "oily" film, dust, etc.
Hey btw, I see you're also in d/fw.... Email me johntori@home.com and I will give you some info on joining our Marine Aquarists Society in d/fw!
