what kind of yeast to use in DIY CO2 ?
i've set up a diy co2 thing to one of my tanks and currently am stuck on reagents for it.
i bought a bred yeast which comes in blocks but not sure its the right way to go.
alternatively i can buy wine yeast, champagne yeast and beer yeast from local brewery. they are kinda pricey tho (5g/2eur).
so the question is what kind of yeast i want to run nice and long?
