Yeah man, back in my FW days I had a 50gal FW tank and did the "yeast in a 2L pop bottle CO2 generator" trick feeding a DIY CO2/water diffuser thing. Worked pretty well actually!
I have a fresh water planted tank and plants are thriving ! with addition of the DIY yeast Co2.
The best is to inject Co2 in to a canister filter intake to disolve it completely.
