I was also thinking, maybe I could use a drop checker. It shouldnt be affected at all by any buffering of the salt water.
I don't think alkalinity is the thing that distorts the accuracy of the calculation.
I'm only guessing at this point but the equations takes kh
in to consideration regardless of what the level is. As the only other thing required to calculate co2
is ph I think it is the other acids/bases in the water that effect ph that makes it difficult to calculate. In order to get a true representation if co2
, you would have to be certain that co2
was the only determining factor of ph.
So it would seem that this chart is accurate because it is assuming that the specified ph level is co2
dependent which makes the calculation relevant however that is simply not true in our tanks because of the unknown variables that may be contributing to the ph level.
My understanding could be wrong though.
