- Ensures proper gravity of aquarium water. Easy to use.
- Ensures all water has the same salinity within aquarium
- Green indicators are ideal range of water temperature and specific gravity for most salt water / marine aquariums.
- Measure both Temperature and Specific Gravity of the water.
- SIZE：19.2CM(7.5″). Glass Hydrometer; Measures Celsius and Fahrenheit
The Living Sea Hydrometer is important to maintain proper living conditions for your fish.
The use of the hydrometer is important to check specific gravity of aquarium water and to ensure all replacement water has the same salinity as your aquarium.
