Red Sea Salt


Red Sea Salt

Premium grade, moderate Alkalinity

Red Sea Salt contains moderately elevated and balanced levels of the foundation elements (Calcium, Magnesium, Bicarbonates) necessary for sustainable coral growth.

When combined with our reef care recipes, it will maximize pigment saturation to bring out your coral’s most vivid colors, while encouraging growth up to twice the natural rate. Red Sea Salt’s Alkalinity of 8dKH makes it ideal for all reef aquarium types, and especially SPS dominated tanks. In addition, with higher dissolvability of our new & improved formula it only takes about 20 minutes from bucket to tank, which makes your mixing routine far more convenient.

Natural seawater includes over 70 elements. Most of them influence the water parameters, but only a few play a significant role in its overall chemical stability. These elements form the foundation of the reef environment and include three major elements: Calcium, Magnesium, and Bicarbonates.

The three ‘foundation elements’ have a major effect on pH stability, Alkalinity, seawater ionic strength, and many of the coral’s biological processes (skeleton formation, ion-exchange, photosynthesis).

Unlike the natural reef environment, where there is an immense reservoir of the foundation elements, the reef aquarium has limited resources that are quickly depleted by the aquarium inhabitants. Therefore, in order to enable sustainable coral growth, it is necessary to maintain higher than natural levels of the foundation elements.

Original research carried out in Red Sea’s laboratory has shown that when increasing the levels of the foundation elements above the levels found in natural sea water, in a very specific ratio , will enhance coral growth and the formation of a robust aragonite coral skeleton.

Red Sea Salt is made according to these ideal ratios, removing the need to adjust the levels of foundation elements after water changes, and providing your corals with a healthy and stable home.

  • All-natural and Eco-friendly
  • Biologically balanced levels of foundation elements
  • Full complement of trace elements
  • Guaranteed parameters for 10 liter / 2.5 gal mix.
  • No toxic levels of Heavy Metals
  • No chemical binders
  • Low moisture content
  • 22kg bucket

Never mix salt in an aquarium containing animals. Always use clean, non-toxic utensils.

  1. Prepare the quantities of salt and water for the desired salinity according to the chart.
  2. User reverse osmosis (RO) water at approximately 20 degrees Celsius. Always add the salt to the water.
  3. Mix vigorously (without aeration) for 20 minutes – 2 hours, until all of the salt is dissolved and pH has stabilizes to 8.2 – 8.5. DO NOT mix for more than 4 hours.
  4. Raise the water temp to 25 degrees Celsius and measure the salinity with an accurate refractometer. Add salt or water as necessary to achieve the desired parameters.
