This glass CO2 drop checker is used to monitor the CO2 dosing in your aquarium. Simply fill with CO2 indicator solution and the solution will change colour to indicate the level of CO2 in the aquarium water. Please note; this listing is for the glass piece / suction cup only. The full kits, including indicator solution, can also be found on the website.

The U-shape (technically it's n shape) enables the drop checker to be fitted over the rim of the aquarium. This makes it easier to analyse the colour of the drop checker, as there is less glare from lights or the aquarium glass itself. It also reduces the amount of equipment within the aquarium, leaving the space clear from distractions.
