Two things:

(1)I have a CO2 calculator that solves for any unknown at 
http://www.bakerweb.biz/fish/co2calculator.html in case you need to 
figure things backwards.

(2) I think it would be easier just to alter the CO2 setup rather than 
trying to arrive at a perfect recipe. Just adjust the location of the 
CO2 output to increase/decrease the efficiency until you get the level 
you want.
