Seachem Glass pH Checker 25mm

Product details

Seachem Glass pH Checker 25mm (3152) is a glass pH monitoring device designed for aquarium use. It helps you observe pH changes using a pH-sensitive indicator solution that shifts color when exposed to the water. In planted aquaria—especially setups that run CO2 injection—the pH checker provides an easy visual readout related to CO2 impact (via pH response), making day-to-day monitoring simpler.

Features:

• Glass pH monitor that reads pH by using an included pH-sensitive indicator solution
• Color-changing indicator (yellow to green to blue) for quick visual interpretation
• Designed to be submerged in the aquarium, with the indicator contained in a small bulb
• Includes a suction cup for attachment
• Usable in essentially any aquarium size
• Helpful for monitoring pH trends in planted aquaria using CO2 injection systems

Specifications:

• Model/size: 25 mm (3152)
• Indicator system: Included pH-sensitive indicator solution with color shift
• Color interpretation: More yellow = lower pH / more CO2; more blue = higher pH / less CO2
• Indicator fill amount (per use): 20 drops of indicator solution in the small bulb
• Attachment: Suction cup included
• Placement guidance: Place at the furthest point from any diffuser
• Aquarium compatibility: Works with any size aquarium
