CO2 Checkers
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. Cal Aqua Labs' CO2 checkers allow you to monitor the CO2 level inside your aquarium. Handmade from the highest quality borosilicate glass, the CO2 checkers are an elegant addition to your planted aquarium.
