For the growth and well-being of reef-building corals, a sufficient supply of strontium is similarly important as the availability of calcium and magnesium. Although strontium is present in seawater in considerably smaller quantities, biological processes, precipitation and incorporation into the calcium skeleton can still lead to a strontium deficiency.

Ingredients

strontium, calcium and sodium salts, bicarbonate, trace elements

Application & Dosage

Add Tropic Marin® Bio-Strontium directly on the surface of the aquarium or sump water, while stirring. Take care that no undissolved crystals come into contact with the creatures. One level measuring spoon (5 ml/0.17 fl.oz.) increases the strontium level of 100 l (26 US-gal.) by about 5 mg/l (ppm). The natural concentration of

seawater is 8 mg/l (ppm).

Basic dosage: 1 level measuring spoon per 50 US-gal./190 l every two weeks is recommended. In an aquarium with a high population, the dosage can be doubled.

Attention: High strontium concentrations in the aquarium may damage corals. Ensure to monitor the strontium concentration.
