The measure of salinity (saltiness) levels in water is Specific Gravity (S.G.). The SeaDrometer is a scientific instrument used to measure the correct salinity level for the type of marine creatures in your set-up. The fishes' indigenous region dictates the level of salinity they will tolerate. e.g.

REGION S.G.		Range Tolerated
Indo Pacific	=	1.018 to 1.022
Caribbean	=	1.020 to 1.025
Red Sea	=	1.028 to 1.034

If the S.G. reading is too low, add Waterlife Ultramarine sea-salt to increase the S.G.
If the S.G. is too high for the species being kept, add fresh-water.
N.B. Always effect changes to S.G. of your system gradually so as not to cause shock to your fishes.

Info:

• Easy to use method of measuring the S.G. of your marine system
• The SeaDrometer has a good range (1.010 to 1.030)
• It is an accurate measure of salinity (accuracy 0.002)
