- 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. It can also be used as a portable device, allowing you to take samples simply by submerging it in the water.
- It features large, easy-to-read markings with ideal salinity range clearly marked in green for clarity.
