Re: [APD] Re: Can one just give up? - Similar story
Good points. I don't think a real level of 30 ppm is
harmfull, or even 40. But given that things other than
carbonates can affect pH, margin of error in measurements
(especially on one is using color-match pH test kit, the
real CO2 level can be considerably higher or lower than
what we impute using the CO2/pH/KH table. While anything in
the 15-30 ppm is probably pretty good, and anything up to
40 is very tolerable, at least for most fish, monitoring as
one ramps up the CO2 is a very prudent suggestion.
