UNS Drop Checker
The UNS Drop Checker is a glass CO2 aquarium gas indicator that takes the guesswork out of pressurized CO2 dosing, shifting colors automatically based on pH fluctuations from dissolved gas: blue means low CO2, green is optimal, and yellow warns of dangerously high CO2. Available in SD in-tank suction or HD over-the-rim hang styles, the kit includes the glass drop checker and a starter 15ml bottle of indicator solution.
