Oil slick

[Garrett706]

I've begun to get some kind of oil slick on the top of my water.

It smells very fishy.

Anyone know what this is ?

Here's what it looks like at night

It's protein film. A skimmer and overflow will help clear it up.

You need more surface movement ,
Move your power heads up or point them up to move the water on the surface .
Water movement is one of the most important things and the most over looked problem .

That makes sense because I just moved my powerheads about a week ago and I never had this problem before

You can also consider adding a surface skimmer.

I had this problem before and researched water circulation and gas exchange .
Surface movement is really important .
Water breaking the surface leaving no standing water or anywhere for this gas/ sludge to sit .
I don't think it's good ,
And have heard of complete tanks crashing cause of It
