Description: 1. Easy to use. 2. Green indicators are ideal range of water temperature and specific gravity for most salt water / marine aquariums. 3. Hydrometer measures specific gravity. 4. Need it for raising brine shrimp. CONTINUOUS USE:1.Submerge the hydrometer approximately 15cm(5.9 in) below the water’s surface.2.Recommended specific gravity should read 1.020-1.023 for most marine aquariums.You must add marinemix when below this level, or add fresh water if above this level.Patented Features:1.Almost no bubbles.
2.Inside mountable for continuous reading.
3.View temperature and specific gravity simultaneously.
4.Use continuously or periodically.
