Indicator Solution works with the indicator device to provide and indicate an accurate reading of CO2 in the aquarium.

CO2 is one of the key elements for plant growth. Insufficient CO2 will result in improper growth of aquatic plants. On the other hand; over supply of CO2 is dangerous to fish and other aquatic life. Therefore it is important to constantly monitor CO2 to ensure the correct amount is supplied into the planted aquarium. Use of a bubble counter can only predict the amount of CO2 by counting the releasing bubbles from the CO2 supply. Dymax CO2 Indicator Solution is a solution that works with the indicator device to provide and indicate a scientifically accurate reading of CO2 content in the aquarium. This solution clearly indicates the concentration of CO2 by changing its colour. With this indicator solution monitoring of CO2 content is more efficient and accurate.
