Seachem pH Checker

Seachem pH Checker is a convenient, continuous pH monitoring device that allows aquarists to visually monitor aquarium pH at a glancewithout test kits, strips, or liquid reagents. Once placed inside the aquarium, the color-changing sensor provides a constant indication of current pH levels.
