Rhinox Glass Drop Checker Kit – 3 Seconds to Read CO2 Levels - 3 Minutes to Setup - Fastest Way to Ensure Sufficient Co2 in Planted Aquarium - Color Change Reflects the Level of CO2;

Keeping an aquarium is both an art and a science. Designing an aquascape and making sure it has all the elements it needs to stay alive and thriving is no easy task. One of the things owners have to look out for is to keep a right amount of CO2 in their tanks. CO2 or carbon dioxide is essential to a tank, it keeps plants happy and producing oxygen that's beneficial to your fishes.

One way to know if your aquarium has the right levels of CO2 is to test them with the Rhinox Glass Drop Checker. Made from high quality glass that's easy to see even in a busy tank, this comprehensive drop checker kit has everything you need to test for a healthy level of CO2.

Every kit comes with 1 glass drop checker, 1 suction cup, 1 10ml CO2 indicator solution, 1 2ml syringe and 1 colour chart. Simply add 5 drops of CO2 indicator into the glass checker and make sure it is stored in the bulbous side of the valve with the opening facing down. Attach this to the side of your tank with the suction cup, completely submerged in the tank water and wait for up to 2 hours. If the blue CO2 indicator turns green, that's the right balance of CO2. If it turns yellow, your tank has excessive CO2. Make the necessary adjustments, empty your glass valve and repeat the test until you get green. A healthy tank has a carbon dioxide to water level that contains anywhere between 20 to 40 ppm (parts per million). 30 ppm is the optimal level that is healthy for both plants and fish.

So the next time you are worried about your plants and fishes having too much or too little carbon dioxide in the tank, keep your hobby worry-free and enjoy your time as an aquarium owner with this easy-to-use Rhinox Glass Drop Checker Kit.
