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 as calcium can easily permeate through your filter 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 phase.
  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.
