Too little CO2 limits plant growth while too much can stress or harm fish. The UP Aqua Drop Checker provides a constant visual reference using a color changing indicator solution helping you dial in CO2 injection safely and effectively. How It Works A drop checker uses an indicator solution with a known KH and a pH sensitive dye. As CO2 diffuses into the solution it changes pH which results in a visible color change.
