DIY CO2 brown+white sugar

Has anyone done 1 cup of each brown sugar and white? I ran out of brown so I did half and half. What were your results?

Also, I'm fairly new to diy co2, this is my 3rd batch ever and all of my batches have looked like this initially:

Attachment 46676

Is this what it's supposed to look like? This was 7 minutes after I shook the mixture and attached it to the tubes.

I'd put a few drops of cooking oil in there...if that starts foaming up you're gonna have yeast gunk everywhere. Oil breaks the foam's surface tension and keeps it down.

My latest experiment is with 1c white and 3/4 cup light brown. Excellent results I must say.

Odd though...I never have the foaming up like most people get. I only get a small amount. I wonder if that has to do with the type of yeast?

FYI, brown sugar is just white sugar with molasses added back in.

A lot of people use brown sugar or straight molasses. It is supposed to make the reaction slower and last for longer periods and not fluctuate as much. I use brown sugar with great results.

I get just a little foam, not much. I just use white sugar, no brown. No molasses.

Get a separator bottle in that system to greatly reduce the chance of gunk ending up in the tank.

...or just put a couple of drops of oil in. Gunk won't end up in the tank if it doesn't foam up there.
