Re-Mineral Tropic

For hardening reverse osmosis water and soft tap water with valuable minerals



Product description

In an aquarium, water changes and the topping up of evaporated water frequently take place using reverse osmosis water. However, reverse osmosis not only removes the harmful substances but also valuable minerals. Tropic Marin® Re-Mineral Tropic adds all natural minerals and active ingredients to pure water that are essential for the health and well-being of fish, as well as lush plant growth. The important carbonate hardness is raised to the optimum value and stabilised. It is also suitable for the conditioning of excessively soft tap water and rainwater intended for aquarium use, as well as other soft water.


Due to its purely natural composition, Tropic Marin® Re-Mineral Tropic is recommended for use in particular with sensitive fish and plants.
