The LaMotte 6917A-J Total Hardness Tablets are a crucial component for determining water hardness levels. They are specifically formulated to work with compatible LaMotte water test kits, providing reliable results for various applications, including pool and tap water analysis.
Setup and Compatibility
These tablets are intended for use as replacement reagents in the following LaMotte water test kits:
- LaMotte 3608 Tapwater Tour Test Kit
- LaMotte 5914 Funky Faucet Sink Science Kit
- LaMotte 5918 Urban Water Test Kit

Operating Instructions
The following is a general procedure for using LaMotte Total Hardness Tablets. Always consult the specific instructions provided with your LaMotte test kit for precise, detailed steps and interpretation of results.
- Prepare Sample: Fill the designated test tube or vial from your LaMotte kit with the water sample to the indicated fill line. Ensure the sample is representative of the water you wish to test.
- Add Tablet: Carefully remove one LaMotte 6917A-J Total Hardness Tablet from its blister pack. Drop the tablet into the water sample in the test tube. Avoid touching the tablet directly with your fingers to prevent contamination.
- Dissolve Tablet: Cap the test tube securely and invert it repeatedly or swirl gently until the tablet is completely dissolved. This may take a minute or two. Ensure no undissolved particles remain.
- Observe Color Change: Once dissolved, observe the color of the water sample. The color will indicate the total hardness level according to your specific LaMotte test kit's color chart or titration method.
- Interpret Results: Compare the color of your sample to the color standards provided in your LaMotte test kit. Follow the kit's instructions to determine the total hardness concentration (e.g., in ppm or grains per gallon).
Maintenance and Storage
Proper storage of your LaMotte Total Hardness Tablets is essential to maintain their efficacy and shelf life.
- Storage Conditions: Store tablets in their original packaging in a cool, dry place, away from direct sunlight and extreme temperatures. High humidity can degrade the tablets.
- Keep Sealed: Only remove a tablet from its blister pack immediately before use. Do not expose unused tablets to air for extended periods.
- Expiration Date: Check the expiration date on the packaging. Do not use expired tablets, as they may yield inaccurate results.
- Disposal: Dispose of used tablets and expired packaging according to local regulations.
Troubleshooting
If you encounter issues while using the LaMotte 6917A-J Total Hardness Tablets, consider the following common problems and solutions:
-
Tablet Not Dissolving:
- Ensure sufficient mixing (inverting/swirling).
- Check water temperature; very cold water may slow dissolution.
- Verify the tablet is not expired or compromised by moisture.
-
Inaccurate or Unexpected Results:
- Confirm the tablet is not expired.
- Ensure test tubes/vials are clean and free of residue.
- Verify the water sample was collected correctly and is representative.
- Review your specific LaMotte test kit instructions to ensure all steps were followed precisely.
- Avoid contamination from other chemicals or substances.
-
Tablets Sticking Together or Discolored:
- This indicates exposure to moisture or improper storage. Discard affected tablets and ensure proper storage conditions for the remaining ones.
If problems persist, refer to your specific LaMotte test kit's troubleshooting guide or contact LaMotte customer support.
