Ailindany CO2 Drop Glass Checker

This CO2 drop checker is made from glass, providing durability and stable test results for monitoring CO2 levels in your aquarium. It is designed for use in fish tanks, particularly those with aquatic plants and tropical fish.

To use the drop checker, install it approximately 3.94 inches (10 cm) below the water surface. It is advisable to place it close to the CO2 diffuser for accurate readings. The device features a suction cup design, making it easy to attach to the wall of your fish tank.

To conduct a test, ensure the drop checker is clean. Add 5 drops of CO2 indicator solution (not included) into the glass checker. Then, use a straw to fill the testing area with aquarium water until it reaches half full. Position the opening of the drop checker facing downward and secure it to the side of the tank using the suction cup. Wait for up to 2 hours to observe the results.

The package includes one glass checker. The color indicators are as follows: blue indicates insufficient CO2, green shows sufficient CO2, and yellow signals excess CO2.
