Hard corals need Strontium as well as calcium to form their skeleton.

In the ocean, currents provide all the necessary elements. In the closed environment of the aquarium, Strontium demand is constant so its input is necessary.

STRONTI + provides the Strontium needed and stimulates growth of hard corals and clams and the production of pink calcareous and encrusting algae that produce the décor.

The decisive advantage:
Adding 1 ampoule of STRONTI + you know that you are adding 130mg of strontium in the aquarium.

Average Dose: 1amp per 400liters or (105gal) every week (add this information to every size of this same additive).
