Tetra Test Marine pH Kit, 50 tests. My first choice in Marine pH kits for ease of use and
ease of read due to significant color differences. Cost is low or comparable to other kits as well.
Tetra -- Information from mfgr:
Tetratest pH Saltwater Kit
- Enough test reagent for fifty tests
- Includes test vial, color scale and instructions
The pH value of water is a measure of the degree of acidity or basicity, with values ranging from 1
(acidic) through 7 (neutral) to 14 (basic). The Tetratest pH kit was professionally developed to accurately
determine the pH level in your aquarium water. The kit contains one 10-ml test reagent (enough for 50 tests),
a test vial, color scale, instructions and recommendations. Test the water in your aquarium weekly to ensure
optimum water quality.
