Fritz Aquatics Wide Range pH Aquarium Water Test Kit, 250 Tests

Fritz Aquatics Wide Range pH Liquid Test Kit measures pH in aquarium and pond water, with liquid reagents for up to 250 tests.

• Wide-range pH testing — check an important water parameter for aquatic environments.
• For freshwater and saltwater — use it with either type of aquatic system.
• Liquid reagents for 250 tests — monitor water repeatedly over time.
• Fast-acting test with easy-to-understand results — compare the sample with the pH color chart.
• Suitable for aquariums and ponds — monitor pH in different aquatic setups.

Water pH indicates whether a sample is acidic, neutral, or alkaline, and it can affect fish, plants, and other aquatic inhabitants. This liquid test kit is made for aquarists and pond keepers who want to check pH as part of maintaining suitable water conditions.

Can this kit test freshwater and saltwater?

Yes, the Fritz Aquatics Wide Range pH Liquid Test Kit is designed for both freshwater and saltwater samples. The two types of water have different result readings, so use the matching freshwater or saltwater results on the pH chart.

• Tests pH specifically across a wide range.
• Use the chart for the type of water being tested.

How do you use the liquid pH test?

Fill a clean test tube with 5 ml of the water sample, add 3 drops of pH reagent, then cap and gently shake the tube several times. Hold the dropper bottle completely vertical while adding drops to help keep each drop consistent.

• Push down while turning to open the childproof safety cap.
• Always use the test tube cap during mixing.
• Keep test solutions out of the aquarium or pond.

How do you read the pH result?

Immediately compare the sample’s color with the pH chart; the closest color match indicates the water’s pH. For a clearer comparison, view the tube against the white area beside the chart in a well-lit location with the light source behind you.

• Avoid skin contact with the test solution, as it may affect results.
• Rinse the test tube with clean water after every use.

This kit suits new and experienced aquarists, aquarium owners, and pond keepers who want a straightforward way to monitor water pH. It measures a parameter that matters to aquatic life without requiring a complicated testing process. Its freshwater and saltwater directions, liquid reagent, and color comparison method make it useful for routine checks across different aquatic environments. For buyers seeking a pH measurement tool rather than a water-treatment product, Fritz Aquatics provides a wide-range liquid test with enough reagent for 250 tests.
