Clear stuff covering pumps & some rocks?

[SamMule]

Been seeing a lot of this stuff lately. Mostly on my pumps/power heads and on some of my rocks. It's almost like a clear film. Bacterial bloom?

That's what mine looked like for a couple of days before it started covering my glass and rocks as well. Is your water cloudy at all?

No, stays pretty clear. Except when my skimmer is blowing bubbles... That's a whole 'nother story...

This stuff has been around for the last few months. Basically, since I increased feeding. Nutrients aren't anything crazy.

I get algae accumulation on the glass about every 2-3 days that needs to be scraped off.

Corals are doing great since I started feeding more, but just wasn't sure what this stuff is. More curious than anything.

Bacteria slime.
