Whoa!  Near as I can tell, my 50 tall uses about 1l/day and CO2 weighs
about 2g/l.   So 1.5kg would last me nearly 3 years.   I would suggest
that either a lot is being lost to the atmosphere (and not dissolved
in the water) or that you have a really high CO2 level.  

My questions:  What does anyone use for hardware that is easier/less
messy than diy yeast and cheaper than hundreds of $$$?

What evidence is there that any level of CO2 over 10ppm is useful? 
More is not necessarily better, you know. 

Thanks.  Dave
