I just started my first DIY co2, and it's been working nicely. I noticed today that there is some sort of film/glob forming on the airstone. Is this normal? What's the procedure, should I be alarmed?
 
it's a very light brown, and kind of hard to see in a picture. It's forming on the side of the airstone that the bubbles are coming out of.

I kept the water level low, so I've not had any froth coming through the tube that I can detect.
 
I remember that I had a kind of a slime coating form on one of my airstones that kept coming back for a while. I just would scrape it off with my fingers when it reformed. is your tank a new setup?

I remember that "slime"; and actually, I have had it form on the airstones delivering bottled Co2 into tanks, occasionally (slightly different color, if I remember correctly.) It appeared, to me, to be some type of anaerobic bacteria feeding there; I mean, this is purely speculation on my part?

I do know one thing, my guppies, platys and snails loved the stuff, and devoured it with gusto!

Naw, it's been going most of a year. I have, however, been experiencing an explosion of hair/beard algae for a few months. The co2 I started this week as part of an effort to eradicate it.
 
Its the muck from the co2 solution.
Just clean the air stone off.
If you use a gas seperator/diy bubble counter, you'll get it less often.It collects most of the muck in its bottle.
