🫧 Aquarium CO₂ Calculator

Dial in high-tech planted tank CO₂ injection. Calculate dissolved CO₂ concentration (ppm) from pH/KH equilibrium, simulate 4 dKH drop checker reagent colors, and estimate cylinder gas lifespan.

Carbonate Hardness (dKH)

CO₂ Injected Peak pH

Degassed Base pH (CO₂ Off)

Diffuser Type

Dissolved CO₂ Concentration

30.1 ppm

4 dKH Drop Checker

Lime Green (Optimal)

1.0 Full pH Drop Target Δ 1.00 pH (Target Achieved)

A true 1.0 pH reduction from degassed water guarantees approximately 30 ppm CO₂, bypassing false readings from driftwood tannins or soil humic acids.
