Salt:  Tropic Marin Reef Salt - Used Exclusively at AquaCorals!

To Mix:  Apply 1/2 cup salt per gallon of freshwater (Kent RO filtered is best).  This is approximate!  Always check salinity with a hydrometer or refractometer!  A refractometer is best!
There are lots of different salt choices but only one meets the AquaCorals standard.  Once I started using this salt it eliminated the need to dose trace elements!  Think of salts like cereal.  You have children & can only feed them "Captain Crunch" or "Total".  Which will it be folks?!  :c)
