  1. Make sure you are not rinsing your cuvettes with tap water ever, regardless of the test. This can lead to inaccurate readings from tap water contaminants.
  2. Make sure you rinse your phosphate cuvettes with RODI after each test before you store them. When you want to perform a new phosphate test we recommend rinsing the cuvettes with 10 ml of saltwater sample a few times before you zero out the Checker. This would help reduce the interference of contaminants that can impact your phosphate readings.
  3. Make sure you are not testing phosphates after cleaning algae in your aquarium or feeding your livestock. This will cause a false high reading.
Make sure you are not using a syringe to fill your cuvettes that have been used to feed fish/coral as this will cause false high readings.

Calcium Checker Troubleshooting Tips

  1. Never rinse your cuvettes with tap water or saltwater
  2. Use pure vapor distilled water from your local pharmacy at C1 phase. RODI water from home filtration units may not be suitable for this test calcium can easily permeate through your membranes.
  3. Clean your cuvettes with distilled or deionized water absent of Calcium that is going to be used for C1 phase dilution.
  4. Measure out 9 ml of distilled or deionized water for C1 phases
  5. Make sure no excess aquarium sample saltwater is on the tip of the pipette. Only administer the saltwater that is sucked into the pipette tip.
