Constantly effectuated quality monitoring, on which you can rely on.

The hw-Marinemix® marine salt formulations offers a highly pure marine water with optimal water parameters,  suitable for all kind of marine life forms. The provision of absolute pure and nature like marine water is the indispensable presupposition for successful Reef- and Marine Aquarium keeping.

hw-Marinemix® professional and hw-Marinemix® reefer are produced in our own production plants in Krefeld, in one of the most modern production plants for synthetic sea salt in Europe. All parts coming into contact with the product are made of stainless steel or high-quality synthetic materials, so that impurities due to production are reliably excluded.


The Bio-Elements (or also called bioactiven substancen of the natural marines water) in hw-Marinemix® formulations.

Since the early 1980er the hw-Marinemix® formulations are already equipped with the bio-elements like they are also present in the natural marine environment. It was a discovery made and brought to production line status by hw Wiegandt in the formulations of hw-Marinemix®.

Bio-elements* (so-called bio-catalysts: enzymes, hormones, vitamins) are purely organic substances, which are present in natural sea water and have important functions. Bio-elements are responsible for the metabolism and largely regulate growth, vitality, blood formation, mating behavior, cell reproduction and resistance to infectious diseases. The resultant effects on marine animals and algae not only enable optimal keeping, but are also a precondition for successful breeding and sets standards for marine aquaristic.

The trace-elements in hw-Marinemix®

The search for resources and technological developments in general have led to significant advances in the development of analytical equipment and measuring methods, the accuracy of which often exceeds conventional methods many thousand times. The generous provision of research ships with modern measuring technology has enabled in the past 15 years seawater to be tested more accurately using new and more precise methods than has been previously possible. The results show that the majority of trace elements occur in a considerably lower concentration in the sea than previously assumed. At the same time, the existence of several elements in sea water was unable to be proven as previously assumed. We are of the opinion that elements that cannot be detected, even using the latest analytical methods, are totally unsuitable for hw-Marinemix marine salts. The trace elements contained in hw-Marinemix  are introduced as so called „mixed crystals“, a method we have practiced for over 50 years. Only in this way a efficient distribution of the trace elements in the total mixture can be ensured.

hw®-Marinemix reefer

This hw-Marinemix® formulation is specially designed to meet the elevated needs of minerals and specified trace-elements in a reef aquarium and the successful breeding of corals.

hw-Marinemix® reefer is a special designed hw® marine salt formulation with the main focus on meeting and satisfying the requirements of high sophisticated reef aquariums with a strong population of stone corals, crustaceans, scallops and other invertebrates. The process of growth and also the natural pigmentation of organic tissues will be strongly improved and the micro biology of the complete aquarium system will strongly gain on stability.

  • Enriched with Calcium and Magnesium for enhanced coral growth
  • perfectly adapted to the requirements of up-to-date reef aquaristic
  • incomparable Bio-Catalyst-System, basing on the references of natural marine environment.
  • with natural amino acids and a organic stabilized iodine from.
  • Contains all natural elements and trace-elements of natural sea water
  • optimal carbonate hardness / alkalinity and natural stabilized pH-buffer-system
  • free of Nitrates, Phosphates and other unwanted chemical elements
  • High, clear and fast solubility in water

hw-Marinemix® reefer contains all trace-elements present in unpolluted natural tropical marine water, which stays completely and easily soluble thanks to the mixed-crystals in the composition. Micro precipitations of trace-elements like in other marine salts often the case, could therefore not occur with hw-Marinemix reefer.

hw-Marinemix® reefer is an adapted further development of the successfully hw-Marinemix® professional proven for decades and primarily takes the changed requirements of modern reef aquaristic into account.

hw-Marinemix® reefer process a higher Calcium and Magnesium concentration which is a essential precondition for the successful growing of organic reef structures.

hw-Marinemix® reefer makes it possible to cover the always existing increased demand of essential needed elements to ensure a healthy growing and development of marine reef organism, just by realizing the periodically water changes.

hw-Marinemix® reefer also considers the interactions in the water chemistry which occur due to an increased need for minerals, trace elements, amino acids, and bio-catalysts, and compensates all resulting interactions in a natural and to a natural extent.

hw-Marinemix® reefer has been proven beneficial especially when targeting the care and growth of skeletogenic corals and mollusks  and significantly contributes to the healthy  development and colonization of larvae.

Even with most delicate corals the reproduction through fragmentation is enhanced and damages of organic coral tissue will be obviously reduced.

hw-Marinemix® reefer is only produced with raw materials proved by us and meeting our high standards of quality. All used components are also used in the pharmaceutical production (as long as available, highest on the production of pharmaceutical products focused quality level).

hw-Marinemix® reefer is continuously monitored and tested by us providing on this way a high quality and a constant composition. Additionally monitoring and board band analysis through an independent and DIN EN 45 001 accredited testing laboratory is your guaranty for highest hw®-Quality.
