Re-Mineral Marine

Hardening mineral salt for reverse osmosis water and tap water


Product description

In an aquarium, evaporated water is frequently replaced by reverse osmosis water. Reverse osmosis not only removes the harmful substances but also the valuable minerals. Tropic Marin® Re-Mineral Marine returns all natural minerals and active substances to the reverse osmosis water. At the same time, the carbonate hardness is increased and stabilised. Also suitable for soft tap water.



  • for hardening reverse osmosis water with valuable minerals

  • restores minerals to the water, which are lost during reverse osmosis

  • contains all trace elements and minerals in the natural composition of the sea, whereas "classic lime water as per Wilkens" only adds calcium

  • increases and stabilises the carbonate hardness

  • also suitable for the conditioning of tap water that is too soft

  • does not contain sodium chloride (table salt)



Calcium, magnesium, potassium and sodium salts, bicarbonate and carbonate, trace elements.


No nitrates. No phosphates. Without sodium chloride (NaCl).
