Carbon Dioxide

Background Information

Carbon dioxide in the water is in the form of a dissolved gas. Aquatic plant life depends on carbon dioxide in the water in order to survive. However, higher levels of carbon dioxide in the water make it difficult for fish to use the limited amount of oxygen in the water. Usually as the dissolved oxygen levels decrease, the carbon dioxide levels increase.

Test Procedure

To perform the carbon dioxide test, use the carbon dioxide test kit from LaMotte (or other supplier). Follow the instructions provided with the kit. Record results in parts per million (ppm).

What to Expect

Surface waters should have a carbon dioxide level less than 10 ppm.
