- Good CO2 levels: 15-35ppm
- High CO2 levels: Over 35ppm
- Low CO2 levels: Less than 15ppm
- This calculator is only accurate if no phosphate buffers such as pH-Up, pH-Down and Discus Buffer is present.
- Do not be misled into thinking that CO2 level can be adjusted by adding chemicals to alter the KH or pH.
- For the most accurate estimation, CO2 must be the only thing affecting pH.
- Formula 1: CO2 = 3 * KH * 10(7-pH) (KH in degrees)
- Formula 2: KH(degrees) = 0.056 * KH(ppm)
