Yeast Based CO2

BTW the mix we are discussing and the bottles is reffered to as a DIY CO2 generator for those who would like to do further research on the subject. Once one get's ones head around what is a generator and what is co2 reaktor things become a little more clear.

Does anybody know what ppm the sera test kit changes colour at? (other than what sera thinks is the right amount.)

Brad i'm not sure but I suspect it just measures the ph as it goes blue when the water is alkaline and yellow when it's acid and green when it's neutral........

Really it just alerts you if their is a problem.

You need to get a KH test kit and a PH test kit then check your results aginst a Co2 chart in order to get the info you are after.

Any one attempting to control a planted tank should at the very least have a KH PH and Fe test kit !!!

Cheers,
