Salinity

The Salinity test comes is performed using a hand held refractometer

What the test is used for:

 Testing Salinity allows us to determine the salt concentration in the tank. 

Effect of Salinity on Aquarium:

 The salinity has a drastic effect on the aquarium, as it is the
 concentration of the NaCl in the aquarium.  The aquarium
 life has a dependence on a certain concentration of salt,
 so if the concentration is not close enough to what the 
 species need, it could result in death of the species.
  

Test Procedure:

 1) Open the plate near the angled end of the refractometer
 2)  Place a couple drops of aquarium water onto surface
 3)  Close the plate carefully
 4)  Read the measurement by looking through the end of the device

Recommended Salinity:

 For the Purple Sea Urchin, the salinity should try to be kept around 
 1.0264 sg.  The unit of measurement is specific gravity.
