Why
should I measure the salinity?
Specific
Gravity (S.G.) is the term used for the measurement of the density
or saltiness of seawater. Maintaining the correct natural levels,
will reduce fish stress and reduce
risks of infection.
Below are some examples for fish and invertebrates:

How
do I adjust the salt levels?
If
the S.G. level is too low within the aquarium, then you need to
add more sea salt such as Waterlife 's Ultramarine to increase the
S.G. reading.
If the S.G. level is too high for the species being kept, add fresh-water
to lower
the salt reading.
N.B.
Always make S.G. gradually so as not to cause shock to your fishes.
