Practical Fishkeeping has added a new carbon dioxide (CO2) calculator to its comprehensive range of aquarium calculators.
The program, which is designed for owners of specialist planted aquaria which use CO2 dosing systems, mathematically determines the carbon dioxide level based on the results of pH and KH tests undertaken with standard testing kits.
For more details on how the calculator works and details on dosing with CO2, please check out our Frequently asked questions on dosing with carbon dioxide.
The program was inspired by Chuck Gadd's carbon dioxide calculator on his excellent planted aquarium pages website.
