Tropic Marin BIO-ACTIF Sea Salt 10 kg

The unique sea salt Tropic Marin® Bio-Actif contains natural bioactive substances from the sea that support the microbiology of the aquarium and thus have a growth-promoting and protective effect on the animal life in the aquarium.

The corals thus display bright and vibrant colors in a completely natural way, and skeletal growth and the formation of stronger tissue are stimulated. The reserves built up in this way make the corals more robust and less susceptible to damage. Fish also benefit from the bioactive substances, which promote the formation of an effective mucous membrane coating. The fish demonstrate their improved well-being through increased mating and reproductive activity.

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