- Keep the color charts dry and clean for accurate readings.
- Ensure all reagent bottles are tightly capped when not in use.
Operating Instructions: Performing Water Tests
Always follow the instructions carefully for each test to ensure accurate results. Use separate test tubes for each parameter. Rinse test tubes thoroughly with aquarium water before and after each use.
General Testing Procedure (Example: pH Test)
The following steps illustrate a typical testing procedure using the pH test as an example. Specific reagent drops and waiting times vary for each test.
Video: This video demonstrates the general procedure for using the Pawfly 5-in-1 Aquarium Water Master Test Kit, using the pH test as an example. It shows how to collect a water sample, add reagents, mix, and compare the color to the chart.
- Collect Water Sample: Use the provided dropper to draw 5 mL of aquarium water and fill a clean test tube up to the 5 mL mark.

Maintenance
- Storage: Store the test kit in a cool, dry place away from direct sunlight and out of reach of children and pets.
- Cleaning: Rinse test tubes thoroughly with clean water (preferably distilled or RO water) after each use to prevent contamination. Allow them to air dry.
- Reagent Care: Keep reagent bottles tightly capped when not in use. Do not mix caps between different reagent bottles.
- Expiration: Check the expiration dates on the reagent bottles. Expired reagents may yield inaccurate results.
Troubleshooting
Inaccurate or Unexpected Results
- Re-check Procedure: Ensure all steps, including the number of drops and waiting times, are followed precisely.
- Reagent Expiration: Verify that reagents have not expired.
- Contamination: Ensure test tubes and droppers are clean and free from residue. Rinse with aquarium water before testing.
- Lighting: Perform color comparisons under consistent, natural lighting conditions. Avoid fluorescent lights which can alter color perception.
- Sample Size: Confirm the water sample volume is exactly 5 mL.
Difficulty Reading Color Chart
- Lighting: Use consistent, bright, natural light.
- Background: Place the color chart against a white background for better contrast.
- Eye Level: Hold the test tube next to the chart at eye level.
