Seachem CO2 Drop Checker Kit

Seachem Glassware - CO2 pH Checker

• Monitors pH solution in aquarium
• 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. 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.

Suction cup included.

Directions

pH Checker works with any size aquarium. Holding the funnel side of pH Checker upward fill the small bulb with 20 drops of indicator solution. Slowly turn the funnel side down avoiding any spillage of the solution. Insert pH Checker into aquarium funnel side down trapping air in the funnel. Attach the pH Checker in aquarium at the furthest point from any diffuser.

The color of the indicator solution will change yellow to green to blue according to the pH of the water. A more yellow color indicates lower pH / more CO₂. A more blue color indicates higher pH / less CO₂.
