how the beep beep beep do i get rid of an oil slick at top of tank
 

so half of the top of my tank has an oil slick on it. it is basically everywhere that isnt rippling. so my question is how the heck do i get rid of it and why is it showing up?

its really starting to get annoying. i dont want to skim it out for it to return. Ideally i want to get to the root of the problem.

Point a powerhead at the top get a rippling action going to break it up.....and keep you hands outta the tank a lot of that is oil from your skin

Are you sure its not protiens, it may be your protien skimmer isnt cuttin it

Agreed. I had a bit of an oil slick on the top then I added powerheads (one pointed up), took it away.

Get a glass bowl or pie plate and slowly tip and edge in. The slick will go into the bowl.
Repeat until it is all gone.
Replace the water with salt water.

Lay a paper towel on the surface and pick it up quickly. Works great!
I used to have to do this before I had an overflow.

ive done all of the above
pointed powerheads to the top of the tank, used a plate to pull out the stuff, tried paper towel, nothing works!!

Ive decided to lower my feeders and stop putting my hands in the water for next few days and see what happens.

actually what works well, is an old aquaclear filter and one of those surdace skimmers.

Point a powerhead at the surface towards the overflow. It will work provided you use a big enough powerhead, and you point it in the right direction.

Your not getting real Sea Water from the Gulf of Mexico, are you?? :razz:
