    Cascade Indicator Solution.

    What it is: Colour indication liquid (bromothymol blue) that you add inside the CO2 indicator glass. Use only 1-2 drop mixed with 4dkh Water to fill the indicator.

    What it does: In order for this to work correctly, it requires Cascade Indicator solution (bromothymol blue) to be mixed with 4dkh Water, this changes colour according to the amount of C02 in your tank. When the drop checker is placed correctly in the aquarium, the colour of the indicator solution (bromothymol blue) will turn lime green when the optimal concentration of 30 ppm of CO2 is achieved in the aquarium water. A yellow or blue colour compared against a pH indicator colour chart indicates too much or too little CO2 in the water, respectively.

    • BLUE=Low CO2 levels -> Increase rate of CO2

    • GREEN=Proper CO2 levels -> No action required

    • YELLOW=High CO2 levels -> Decrease rate of CO2

    This set contains: 10ml Bottle Indicator Solution
