Mardel Live pH In-Tank Monitor 3 pack
This in-tank pH monitor makes checking your pH easy, helping to maintain healthy water quality.
The simple and precise device allows you to monitor pH values at-a-glance. The patent pending technology ensures accurate pH values.
To use, simply attach to the inside of your aquarium using the included suction cup. Once fully wet (1-2 hours), LivepH responds to pH changes in minutes. Simply visually compare the active membrane to the color reference blocks to determine pH level.
For best results, replace each LivepH every 4-6 weeks. A pH test is most accurate in correctly buffered water.
Measures 3 3/4"L x 1 1/2"W. For freshwater use.
