S.T. International Aquarium CO2 Long Term Monitor

CO2 (carbon dioxide) is the most important nutrient source to aquatic plants. Plants will not grow with insufficient CO2, even if other trace elements are still supplied daily. However, it can be harmful for fish if the CO2 concentration is too high. Knowing the accurate concentration of CO2 is very important. With our S.T. CO2 Long Term Monitor, you can monitor your CO2 levels by simply looking at a test strip color chart of blue, green and yellow. It is simple and accurate! And it provides easy continuous CO2 monitoring to allow the user to maintain CO2 levels at the optimum range!.
