CO2 Drop Checker Kit

The CO2Art CO2 Drop Checker Kit is a set for monitoring the CO2 level of aquarium water: a glass drop checker with indicator solution.

The kit is made for planted aquariums with CO2 injection and has everything you need to start monitoring.

The drop checker is made of low-iron glass. It is 3 cm in outside diameter and 5.5 cm high. The indicator is a 4 dKH solution whose colour shows the CO2 level in the water.

Fix the drop checker inside the aquarium with the suction cup. Deep green means the CO2 level is right, blue means too little CO2, and yellowish means too much, and the fish can be at risk. The drop checker shows the CO2 level with a delay of several hours. Replace the solution at least once a month.

The set includes the glass drop checker, 15 ml of indicator solution and a suction cup.
