If you have a community reef or a fish only tank with no special requirements and the desired alkalinity range is 7-11 dkH, you should use the Classic Salt Mix.

If you have a reef tank with higher calcium requirements and  there is a desire to maintain alkalinity in the 5.5-9.5 dkH range, you should use the Pro-Reef Salt Mix.  If you have a Ca or Kalk reactor, the Pro-Reef Salt should be used.

If you would like to carbon dose your reef tank and an low nutrient system is desired, then the Bio-ACTIF System salt is the salt for you.
