What's your average cost for each batch of DIY CO2 mixture? How often do
you mix a new one. What size is your tank?

I'm just trying to decide if there's big price difference between going
DIY
CO2 versus Flourish Excel (which is $17.99US for a 8-12 month supply).

You wouldn't need more than a few kilos of sugar and a couple of pots of
yeast to last a whole year, surely.
