For almost 50 years, Tropic Marin has provided true-to-life conditions in aquariums. Saltwater prepared with Tropic Marin Sea Salt forms the ideal biosphere for delicate fish, marine plants and invertebrates, and creates natural conditions for keeping and breeding them with success.
Tropic Marin Sea Salts contain all 70 trace elements in the natural concentrations of the ocean. No more, no less.
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.
