Over millions of years, corals, fishand microorganisms have adaptedto a constant salt composition inour oceans.To create optimal livingconditions for the inhabitants ofyour aquarium's artificial environment,the ions present in marinewater must therefore correspondto those found in natural marinewater, both in terms of compositionand quantity.Marine waterproduced with a salt mixture shouldhave the same ion ratio as naturalmarine water and should not bedistinguishable from natural marinewater.
