NeoMarine Salt

  • A successful marine aquarium begins with quality seawater. Brightwell Aquatics NeoMarine Salt Mix creates this ideal marine environment for aquarium inhabitants by providing all major elements, all non-conservative minor and trace elements, and elements known to be utilized in the production of biological pigments (biochromes) in precise natural seawater ratios. Elements are provided by individual salts (no seawater evaporite is used) enabling consistency in each salt mix. Contains no detectable ammonia, nitrate, phosphate, or organic substances at standard specific gravity. It dissolves completely to create crystal clear water. NeoMarine is formulated for all marine organisms, not just fish or reef inhabitants. NeoMarine is manufactured in the USA.

  • Do not mix in an aquarium containing live organisms. NeoMarine creates slight heat when mixed into water; therefore, do not handle dry NeoMarine with wet hands. NeoMarine may have a slight sulfurous odor when the container is first opened; this is a result of the use of anhydrous magnesium chloride and sulfate and will dissipate. Each 134.5 g of NeoMarine added to sufficient purified water to create 1 US-gallon total saltwater will result in specific gravity of ~1.025 g/cm3. If not using an accurate scale to measure salt, in a clean mixing vessel dissolve approximately 4 oz., or half a cup, of NeoMarine per gallon of purified water and adjust specific gravity as needed by adding more salt or water to increase/decrease specific gravity, respectively.


    It is strongly recommended that water purified via reverse osmosis and/or deionization be used for seawater preparation. Place the full amount of water you intend to mix into a mixing vessel. Heat the water to 76 to 78 deg F first before adding NeoMarine mix. Add NeoMarine slowly, mixing vigorously. Allow the freshly-made seawater to mix thoroughly with a submersible pump for no less than one hour. Always use an accurate hydrometer or (preferably) refractometer to determine the specific gravity of prepared seawater. Ensure that the water temperature matches that of the established aquarium. Allow water to mix, preferably while being aerated, until pH becomes completely stable, indicating that gas equilibrium has been achieved.


    Although water can be used in an hour, It is strongly recommended that at least 24-hours of mixing be allowed to pass before adding the water to an established aquarium; this extra time enables gas formed during the salt dissolution to escape, further stabilizing alkalinity and pH.


    Note that water temperature and mixing rate will influence the speed with which the salt goes into solution. It is recommended that 10-20% of the total water volume in an aquarium system be replaced every 7-10 days; this helps maintain proper water chemistry and consequently benefits aquarium inhabitants.


    Causes of Cloudiness: NeoMarine is an anhydrous salt, meaning that is is much drier than most salts (which are hydrated meaning they contain water, quite a bit of it). If you add NeoMarine to water too fast, it will cloud. It may also cloud if: water is too cold, salt is added too much or too fast, or you don’t use the full volume of water.


    What to do if you have mixed it wrong and it is cloudy: Cloudiness is not dangerous, it is just the formation of carbonates of divalent cations, such as calcium, into tiny particles. When added to the aquarium, it will dissolve over several days. Adding it through a fine filter sock may remove some of the particles and allow them to dissolve unseen, over time.


    Caution: Keep out of reach of children. Not for human consumption. Generates slight heat when added to water; do not handle NeoMarine with wet hands. Contact with dry product may cause skin and/or eye irritation. In case of eye contact, flush eyes with cool water and seek immediate medical attention.
