What are the important considerations when selecting a salt mix for a marine aquarium?
Sea Salts should contain all of the essential major, minor and trace minerals of natural sea water in proper proportions...PLUS.
In the wild, animals have
cubic miles of seawater from which to draw the minerals that
they need. In the enclosed environment of a marine aquarium,
however, animals often suffer because they quickly use up
available minerals. Most sea salts, however fine, only provide
seawater levels of trace minerals rather than enhanced mixes of
both important minerals and minerals plus vitamins for invertebrates.
