Seachem pH Checker

Seachem pH Checker

Seachem pH Checker monitors pH solution in aquarium. Its easy-to-read color changing indicator solution included. Recommended for planted aquaria with CO₂ injection systems.

The pH checker is a glass pH monitor that comes with pH sensitive indicator solution. (For refills, see our CO₂ Indicator Solution). When submerged in water, this indicator solution changes color according to changes in the pH of the aquarium as a result of CO₂ gas. The pH checker makes monitoring CO₂ concentrations and pH level in planted aquaria easy. Remember, when you add co2 – it changes your pH. So you measure your pH to see your co2 levels.

Suction cup included.
