Red Sea Salt is designed to provide exactly the same parameters as tropical reef water with a slightly higher level of alkalinity needed in a closed aquarium system. Red Sea Salt is ideal for fish and invertebrate tanks, or for low nutrient tanks where the enthusiast regularly adds all the individual elements.

Red Sea Salt offers stable seawater with a pH between 8.2 and 8.5.
These parameters are based on a mixture of dry salt with reverse osmosis water.
Red Sea Salt is designed to provide biologically balanced high levels of fundamental elements (calcium, magnesium and carbonates) necessary for the accelerated and sustainable growth of all corals. Salt Coral Pro is ideal for reef aquariums, especially LPS and SPS corals and growing coral cuttings.
Natural seawater contains more than 70 chemical elements and although most of these elements have a great influence on water parameters, some of them play an even more significant role on general chemical stability.
These elements are the basis of the reef environment and include the three major elements: calcium, magnesium and bicarbonates. These three fundamental elements have a major effect on water chemistry (pH stability, alkalinity, ionic strength of seawater) and on many biological processes at work in coral (skeleton formation, exchanges ions, photosynthesis).
Unlike the natural reef environment where the reservoir of fundamental elements is immense, the reef aquarium has limited resources that are quickly depleted by its inhabitants.
This is why, in order to ensure sustainable growth for corals, a greater quantity of fundamental elements is needed than in the natural environment.
Initial research by Red Sea Laboratories has shown that in a closed aquarium system, specific proportions of the fundamental elements calcium, magnesium and carbonates (alkalinity) are necessary for coral vitality and to a robust formation of their skeleton in aragonite. These proportions must be particularly maintained in the event that the levels of the fundamental elements become higher than the levels of the natural environment.

The third element of the Balling method, this "salt-free salt" is a mixture of all the mineral salts present in natural seawater , except sodium chloride NaCl. It allows the maintenance of the ionic balance in the application of the Balling method.
1kg of powder allows the preparation of 41 liters of solution. That's 0€41 per litre!

Very good salt, I recommend it. I've been buying the red sea brand for years, never had a problem. (Translated review)
