Does anyone agree PH/KH
charts are null and void especially if EI dosing or if you have a high tap GH
My degassed aquarium water is 8.4PH and KH
12 which gives me 1.22ppm co2
My tank PH is 7.3 which gives me about 30ppm co2
However according to the chart 7.3PH and KH
12 is only equal to 20ppm co2
My drop checker is 4dkh solution accurate to 0.01 and this is always yellow when my PH is 7.3
At PH 7.5 it goes green and PH 7.9 it goes blue.
Seems paying more attention to the drop checker is better than trusting the ph chart. Anyone have similar experiences?
