Tropic Marin BIO-CALCIUM, 1800 g

Calcium present in seawater plays an important role in the development and growth of marine organisms. Corals and other invertebrates absorb large amounts of calcium from the water thereby depleting the calcium levels and reducing carbonate hardness in the aquarium water. While oceans have vast reserves of calcium, reef aquariums require regular supplements of calcium to maintain optimal levels.

Tropic Marin Bio-Calcium is a calcium supplement for saltwater aquariums with soft and hard corals. The formulation not only increases the calcium level and carbonate hardness, but also stabilises the pH values of the water.

Bio-Calcium does not contain any artificial by-products that could disturb the ionic balance of the water.

Ingredients: calcium, bicarbonate, magnesium, potassium, trace elements.

Application:

In order to use the product correctly, measure the total volume of water contained in your aquarium. Furthermore, you will also need to measure the calcium content and carbonate hardness of the water.

Measure the required amount of Bio-Calcium with the measuring spoon provided. Sprinkle it one spoon at a time the surface of the aquarium water. Add the next spoon only after the first one has dissolved completely.

Dosage:

Use 1 level measuring spoon of Bio-Calcium per 100 L of aquarium water. This increases the carbonate hardness by 1.5 °dH and the calcium content by 10 mg/L.

• Maximum dosage: 2 measuring spoons/100 L of aquarium water per day

Note: It is recommended to keep the carbonate hardness below 9°dH.
