I believe the commonly used CO2 calculator found on this site http://www.csd.net/~cgadd/aqua/art_plant_co2chart.htm is frequently used and discussed on this (and other) forums with regards to CO2 levels and its relationship with kH and pH.
The article states "CO2/pH/KH calculator and chart
NOTE: This calculator (and the chart based on this formula) will only work if your water is carbonate buffered. If your water contains high levels of phosphates, it will alter your water properties, and invalidate these CO2 calculations."
If I'm using CO2 injection with EI dosing, I'm adding excessive amounts of kH2PO4 (Mono Potassium PHOSPHATE) in addition to other ingredients. Well, my phosphate level is going to be high and therefore invalidate the CO2 calculator. How do I resolve this problem so I can calculate CO2 levels properly.
