Fauna Marin Multi Reference – High-Precision Test Kit Calibration

Fauna Marin Multi Reference – High-Precision Test Kit Calibration

Fauna Marin Multi Reference is an essential laboratory-grade solution designed to verify the accuracy of your home aquarium test kits. In the reef-keeping hobby, even the most expensive titration or colorimetric tests can provide inaccurate results due to reagent aging, contamination, or user error. Multi Reference provides a solution with fixed, laboratory-certified values, allowing you to calibrate your kits and calculate a correction factor. This ensures that the parameters you measure—such as Alkalinity, Calcium, and Magnesium—are actually reflective of your tank's true chemistry.

The Ultimate Tool for Testing Accuracy

Multi Reference acts as the "truth" for your testing routine, eliminating guesswork and preventing the dangerous over-correction of water parameters.

• Laboratory Certified: Each bottle is batch-tested and provides a stable reference point for all major reef parameters.

• Broad Spectrum Calibration: Validates a wide range of essential values, including Calcium, Magnesium, Potassium, Alkalinity (KH), Strontium, Nitrate, and Phosphate.

• Correction Factor Calculation: Allows you to determine if your test kit is reading high or low, giving you a mathematical "Correction Factor" to apply to all future results.

• Prevents "Chemical Chasing": Helps avoid the common mistake of dosing chemicals based on a faulty test kit reading, which can lead to livestock loss.

• Cost-Effective Security: A single 250ml bottle provides enough solution for dozens of calibrations, ensuring your testing remains reliable for the life of your reagents.

  Reference Values (Standard Sample)

  Values may vary slightly by batch; always check the label on your specific bottle.

  Parameter	Reference Value (Typical)
  Alkalinity (KH)	6.6° dKH
  Calcium (Ca)	422 mg/L
  Magnesium (Mg)	1315 mg/L
  Potassium (K)	409 mg/L
  Phosphate (PO4)	0.2 mg/L
  Nitrate (NO3)	10.0 mg/L

  FAQ Section: Common Questions

  • How do I use Multi Reference?

    Perform your standard test (e.g., an Alkalinity test) using the Multi Reference solution instead of your aquarium water. Compare your result to the value printed on the Multi Reference bottle.

  • What is a "Correction Factor"?

    If the bottle says KH is 6.6 but your kit reads 7.0, your correction factor is 6.6 / 7.0 = 0.94 Multiply your future tank results by 0.94 to get the true value.

  • How often should I calibrate my test kits?

    It is best practice to use the Multi Reference whenever you open a new box of reagents, if you get an unusual or unexpected reading, or once every 2 months to account for reagent degradation.

  • Does it work with all brands of test kits?

    Yes. Multi Reference is an independent standard and can be used to verify Salifert, Red Sea, Hanna Instruments, Elos, and any other brand of hobbyist test kit.
