Fauna Marin Salinity Reference 35 ppt - 100 ml (17125V)

Precise calibration solution for refractometers, conductivity meters, and salinity pens

Fauna Marin Salinity Reference is the ideal reference solution for checking and calibrating the accuracy of your salinity measuring devices (refractometers, salinity managers, digital salinity pens, etc.).

• Exact value: 35 ppt (corresponds to ~53.0 mS/cm) – the recommended optimal value for most reef aquariums
• Saltwater-based matrix – significantly more realistic than simple NaCl solutions
• Very high precision – manufactured and batch tested according to strict Fauna Marin quality standards
• Easy to use – just a few drops are enough to calibrate refractometers or check the function of digital measuring devices.
• Contents: 100 ml in a practical dropper bottle with child-resistant cap.

Why is the right salinity so important? A stable salinity of 33–35 ppt is the basis for healthy coral growth, good colors, and minimal stress for fish and invertebrates. Deviations indirectly affect almost all other water values – that's why it's worth checking your measuring devices regularly!

Perfect for:

• All refractometers (including non-automatic models)
• Fauna Marin Salinity Manager
• Digital salinity meters (e.g., Milwaukee, Hanna, Apex, etc.)
• Aquarists who want the highest accuracy in salinity control

Tips for use:

• Shake the bottle gently before use •
• Calibrate at room temperature (ideally 20–25 °C) •
• After calibration, rinse the device with RO/DI water
