Pressurized CO2 with DIY mix.. need help please

i have a pressurized co2 canister. one of the hagen ones i think. its gray. anyway i just filled it with the normal amount of sugar to the first line then poured a small bag of yeast. after 10 minutes it started putting out tons of white stuff in it. and now the tank is super cloudy... did i put to much yeast or something?

The Hagen CO2 is not pressurized CO2, but simply DIY CO2.

Do you have a check valve between the DIY mix and your aquarium? From what it sounds like, your yeast mixture got into the tank. I would do several large water changes to get rid of the yeast first.

How much yeast did you use?

A bag of yeast? did you use the hagen pack or like a pack of bakers yeast... If bakers, you used too much. Likely you overfilled the hagen unit. And this is not "pressurized" co2.
