hw sea salts from Krefeld
Use hw Marinemix professional or hw Marinemix reefer to prepare seawater for aquariums. We manufacture our sea salt mixes at our own factory in Krefeld. The parts of the production equipment that contact the product are made of stainless steel or high-quality plastics.
Raw materials, trace elements and bioactive components
Our formulations are based on the composition of natural seawater and include minerals, trace elements and bioactive components. Trace elements are incorporated using the mixed-crystal process. We regularly check the quality and composition of our sea salt mixes.
Prepare seawater to suit your aquarium
Choose the mix according to your livestock and aquarium requirements. Use suitable source water, follow the mixing instructions and check the prepared water before use. Salinity, calcium, magnesium and alkalinity also depend on the amount of salt and the mixing conditions.
Monitor water parameters regularly and replenish consumed substances when testing shows a need. A single measurement does not replace assessment of the overall water chemistry and husbandry conditions.
hw Marinemix reefer
Sea salt for reef aquariums and coral propagation
hw Marinemix reefer is intended for reef aquariums with stony corals and molluscs. The mix is enriched with calcium and magnesium and contains natural amino acids and organically stabilised forms of iodine.
Regular water changes can contribute to mineral supply. High consumption requires additional testing and supplementation according to demand. Coral growth and colour also depend on lighting, water movement, nutrients and other husbandry conditions.
Use suitable source water and follow the mixing instructions. Before use, check salinity or density at the intended temperature, as well as calcium, magnesium and alkalinity.
The carbonate buffer system contributes to buffering capacity. Precipitation depends on water chemistry and the conditions during mixing and dosing. A sea salt mix does not replace monitoring and replenishment of consumed substances according to demand.
We use tested salts of high purity, in pharmaceutical grade where available. We regularly check the quality and composition of our sea salt mixes.

hw Marinemix professional
Sea salt for marine aquariums, research and breeding
hw Marinemix professional is a sea salt mix for marine community aquariums and specialised applications with LPS and SPS corals, in breeding facilities and research institutions.
The carbonate buffer system contributes to buffering capacity. Check water parameters for your livestock or application and supplement calcium, magnesium or alkalinity only when needed.
The parameters of prepared seawater depend on the source water, amount of salt and mixing conditions. Monitor salinity or density and the other parameters relevant to your application.
When testing shows a need, supplement calcium, magnesium or alkalinity with hw CalciumMarin, hw MagnesiumMarin or hw BufferMarin, following each product’s instructions. The carbonate buffer system does not replace regular pH and alkalinity testing. Precipitation depends on water chemistry and the conditions during mixing and dosing.
We use tested salts of high purity, in pharmaceutical grade where available. The mix contains no chemical binding or complexing agents. We regularly check the quality and composition of our sea salt mixes.
