Features

  • Compact design with large, easy-to-read markings
  • Ideal salinity range clearly identified in green for added convenience

Questions & Answers

The specific gravity reading from my hydrometer was very high. What should I do?

Make sure you tap the hydrometer thoroughly to dislodge any air bubbles from the armature. If tapping the hydrometer doesn’t help, insert a thin object into it and tap the armature itself.

At what temperature is the Fluval Hydrometer calibrated?

The Fluval Hydrometer is calibrated to 75°F / 24°C.
