Re: Aquatic Plants Digest V4 #768


i am not sur ei quite understand, and as i am new to this hobby, i hope you 
could explai a bit to me.

there is the pH KH table that tells you how much C02 is in solution. now, the 
more CO2 you add, the lower the pH should go, yes? so if i run my carbo-plus 
at ten bars then the pH should go down (b/c the CO2 forms carbonic acid in 
solution, yes?) and if i run it at 1 bar, then the pH should go up, correct? 
so, i should run the carbo-plus so that, based upo my KH readings (which i am 
not too confident of, i have a tetra test kit - is that good enough or could 
you recommend one?)my pH stays around 6.8? and that will be enough CO2 no 
mater what? what should be my target CO2 levels and KH levels?

all this predicated upon accurate test readigs, which i am not yet cofident 

thanks for your time..
