Highest quality premium marine salt similar to nature The new sera marin reef salt is a highest quality premium marine salt similar to nature for splendid reefs. It is blended from single components and ensures pollutants can by all means be excluded. The constantly high quality reduces stress during water changes.
Dissolve in dechlorinated tap water or water purified by reverse osmosis [4.4 oz./US gal. (33 g/l)]. The salt can be used in the aquarium immediately after brief aeration and vigorous stirring. Use a hydrometer (density meter), refractometer or conductivity meter for adjusting the density (1.022 – 1.024 or 48 – 52 mS/cm). Avoid density variations during water changes and do not prepare concentrated solutions. Never dissolve sea salt directly in the aquarium but in a suitable plastic container! Recommended water change 5 – 10% per week for best results. Use sera aquatan for removing chlorine compounds from the tap water used for preparation, and regularly sera marin bio reefclear for improving the general environment.
