Please note that the Nutrafin system is a manufactured system which does
exactly what your DIY system does. The two packages contain yeast and
sodium bicarbonate, and you supply your own sugar. Given that you
already know how to mix yeast and sugar, you might not be too happy to
pay their price for the little packets.

Enough people have problems with diffusing CO2 that it might be worth it
just for the bubble counter/diffuser module, if it was cheap enough!
