Item # SEA04




  • Fluval Sea Hydrometer provides an accurate and convenient method of measuring specific gravity and salt level in marine aquariums.
  • Regular testing is strongly recommended as stable salinity levels are essential for the health of marine fish and invertebrates.
  • Compact and easy to use, the hydrometer can be permanently installed inside the tank for continuous readings.
  • Its slim, low-profile design camouflages well inside the tank and will not diminish the aesthetics of the aquarium.
