Tropic Marin Bio-Calcium

Enables the addition of biologically ideal calcium to the reef aquarium:

All calcareous animals, especially corals need calcium and carbonates to grow and flourish. However the growth rate of corals depends mostly on the zooxanthellae (algae) that live symbiotically within them. These algae present the coral with precious carbohydrates of their own metabolism. As they photosynthesize, they use carbon dioxide from the water, which enables the coral to precipitate calcium carbonate in its skeleton. Only when calcium and carbon dioxide are available together can this symbiotic relationship work. Tropic Marin Bio-Calcium is the ideal source of both calcium carbonate for the corals and carbon dioxide for the zooxanthellae.

Many calcium supplements add undesirable by-products to the water, or like Kalkwasser, influence pH. When Tropic Marin Bio-Calcium is dissolved in the aquarium, all 70 trace elements are added and no unnatural by-products are formed. Tropic Marin Bio-Calcium will not alter the pH level if used in accordance with the instructions. 

Natural sea water contains on average 400-410 ppm of calcium and is typically saturated at this level. It is important not to exceed 450 ppm, as super saturation can result in the calcium surplus precipitating out of the solution, taking desirable trace elements with it. We recommend the use of a Tropic Marin calcium test kit and Tropic Marin Bio-Calcium to ensure these proper calcium levels.

Tropic Marin Bio-Magnesium

Biologically ideal Magnesium Supplement for Reef Aquariums.

A sufficient supply of magnesium is as essential for the growth and well being of reef building coralline algae as calcium. It is one of the major constituents of seawater and is directly involved in algae photosynthesis, i.e. the conversion of carbon dioxide (CO2) and light into organic compounds. The addition of plain magnesium salt, however, is not sufficient and interferes with the ionic balance of the tank water. Tropic Marin Bio-Magnesium creates a natural environment in the aquarium and delivers Magnesium in a natural biologically available ionically balanced form.

Tropic Marin Bio-Strontium

Biologically Ideal Strontium Supplement for Reef Aquariums. 

A sufficient supply of strontium and carbon dioxide is as essential for the growth and well-being of reef-building corals as calcium. Both elements are supplied to the corals with the help of the zooxanthellae (algae) that live symbiotically within them. Bio-Strontium creates a natural environment in the aquarium and delivers strontium and carbon dioxide in a natural, biologically-available ionically balanced form.
