Hi ...

Can someone tell me if there is any cheaper alternative to the Nutrafin
CO2
refill kits ? Any "DIY" receipt ?

Thanks

It is my understanding that the 2 sachets for the Nutrafin reactor contain
yeast, the other one baking soda.
I simply use the sugar, tepid water and just less than 1/2 teaspoon of
normal bakers yeast, I get about 2 weeks of C02 with this. As yeast can vary
in its potency I would recommend just using 1/4 teaspoon of yeast until you
know how it will behave. Too much yeast and it will froth up into the tank!
