AQUATIC VENTUREZ Pro Glass CO2 Ball Checker
Maintaining the appropriate CO2 level is critical in a planted aquarium. Too much CO2 may harm your fish, whereas too little CO2 decreases plant growth and allows algae to take over. The CO2 indicator makes it easy for you to know the CO2 level inside the aquarium by comparing the color of the reagent.
The CO2 Indicator can be cleaned easily using bleaching agent when dotted with algae. Rinse glass piece thoroughly before putting it back to use. AQUATIC VENTUREZ Pro Glass CO2 Ball Checker are used for long-term monitoring of the CO2 levels in the aquarium. A CO2 reagent is filled into those CO2 Checkers and will change the color according to the amount of dissolved CO2 in the aquarium water. Green will indicate a proper CO2 value, yellow will indicate to much CO2 and blue will show not enough CO2.
