The unique Tropic Marin® Bio-Actif sea salt contains naturally occurring marine biopolymers, which support the microbiological conditions in an aquarium and thus protect and enhance the growth of aquarium fauna.

​

To this end, corals will exhibit their bright and vibrant colors in a natural way, while skeletal growth and/or the growth of stronger tissues are promoted. The reserves built up in this manner ensure that corals are more robust and less sensitive than otherwise. Fish also benefit from the bio-active substances by the formation of effective protection against damage to mucous membranes. Fish will exhibit their heightened sense of well-being by increased mating and reproduction activity.

​

Tropic Marin® Bio-Actif sea salt is suitable for both beginners and advanced aquarists, and ensures stable conditions for all marine organisms at an alkalinity in the range of 8-9 °dH.
