Nutrafin CO2 systems and DIY mixes

[Shouganai]

I have two of the nutrafin CO2 systems I got really cheaply about a year ago, and I've been using them on and off with the mixtures Hagen sells.

I am looking to put one of them on my 20g, but I'm not too keen on buying their mix every time.  Does anyone run one of these and make their own yeast mix? If so, whats your recipe?

I'm just figuring that I'd like to use one or both of these things temporarily since I don't have much time right now to make a DIY system from scratch.

Thanks!

I'd say you could just make your own c02 mix with yeast, sugar and water.  Should work the same.  The diy system sent to me by a fellow memeber recently was

Mixture Formulas

For two-liter bottles:

    * 2 cups water
    * 2 cups Sucrose (cane sugar)
    * ¼ teaspoon Fleischmann's Active Dry Yeast
    * ¼ cup tepid (ideally 104ºF) water

Now just figure out the difference between size of 2 litre bottle and the cannister for your nutrafin system.  Adjust the recipe measurements to what you need.

I think this should work, maybe someone else can tell you better

Here's what I use in the Hagen canister

I use regular old table sugar up to the first line, a couple of pinches of baking soda, add water to an inch or so below the second mark. Then shake the sh... er heck out of it. Prepare yeast (I use about a half teaspoon) as per directions on package. Add yeast to container then top off whatever amount of water to reach the line.

Had great results w/ fleishmans trad baking yeast, but I am currently experimenting w/ various brewing yeasts. Sticking to ones with high alcohol tolerance and a wide temp range. So far I'm less than enthusiastic about the results but will try different concentrations etc.

Here's a site that has a comparison of some different strains
