Reef Salt 4kg Box – salt for marine aquariums

Reef Salt from Aquaforest is a 4 kg box of marine aquarium salt for hobbyists keeping reef and saltwater systems who need a salinity-ready mix prepared from a measured dose. The packaging covers a standard batch: about 390 g dissolved in 10 l of demineralised water gives the 33 ppt (1.025 SG) reference value.

Why it matters

• The mixing ratio is printed on the box: about 390 g per 10 l, so the batch size is easy to calculate for a given tank.
• Each production batch is tested by ICP-OES for composition uniformity and the absence of unwanted contaminants, according to the manufacturer.
• The manufacturer states that a 2–3% variation between containers is acceptable, and that measured deviations are smaller than the typical tolerance of hobbyist test kits.
• Produced in the European Union under laboratory-controlled conditions; batch test results can be viewed online.

Specifications

What it works with

The mix is intended for marine aquariums, including reef tanks, and is used to prepare saltwater from scratch for water changes or for filling a new system. Because the solution changes salinity through evaporation and should be checked before use after several days of storage, it suits hobbyists who prepare saltwater in batches for their tank size.
