Ideal for reef tanks when you want to maintain a high pH.
CO2 is converted into carbonic acid (H2CO3) which lowers your pH. This tool can help monitor your household's CO2 levels, letting you know when to temporarily open a window or when to use calcium hydroxide media (CO2 purification media) to maintain a high pH level.
