Dosing 114ppm CO2? Is this correct?
i have the following "strange" situation with my 58 gal. heavy planted tank.
KH is at 6 degrees, ph is set to 6.2 . this results in 114ppm of CO2 in the tank.
i filled a glass with water from the tank, after 24 hours i measured its KH which for some strange reason was 8 degrees and ph was 7.5 (CO2 = 9.6)
this results in 114-9 = 105ppm of CO2??!!!
am i measuring something wrong here?
please advice on this. i want to make sure that i'm injecting more than 30ppm CO2 (as Tom Barr recommends).
thanks in advance,
