Tropic Marin® Bio-Calcium is a simple and efficient way to raise calcium and alkalinity and to stabilize the pH for optimal growth of corals and coralline algae while creating the ideal conditions for successful reef aquariums.

• Increases calcium and alkalinity and at the same time stabilizes the pH without disturbing the ionic balance.

• No unnatural by-products.

• Maximum recommended dose is 2 measuring spoons per 100 l / 26 US-gal. of aquarium water per day.

• Exact dosages without prior dissolving.

• Can also be used as part of the Tropic Marin® Bio-Actif System.

• Suitable for an aquarium stocked with soft corals, LPS and SPS.

Tropic Marin® Carbo-Calcium Powder is highly concentrated calcium and alkalinity for dissolving in reverse osmosis water to get the proven  Carbocalcium solution.

• Extremely high yield: 1 kg (2.2 lbs.) contains 307 g calcium and approx. 43,000 °dH (alkalinity)

• The pH value remains completely stable

• No phosphates or surplus CO2 are added to the aquarium

• The salinity remains constant (no sodium chloride is created)

• No danger caused by oxygen depletion

• Suitable for all tank sizes

• After mixing, the resulting solution is suitable for both manual dosage and for dosing pumps

• We recommend not to exceed a daily dose of 25 ml of Tropic Marin® Carbo-Calcium per 100 liters (26 US-gal) of aquarium system volume.

Tropic Marin® Coral Clean is phosphate-free and less aggressive than other forms of cleaning baths such as Lugol’s solution or fresh water.

• Cleans corals from the most common epiphytes, parasites and impurities

• Unlike conventional PVP iodine for wound care, with no phosphates

• Gentle treatment of corals

• No stress to the tank from medication or biocides as it used as a bath

• Immediate monitoring of success, any fallen epiphytes and parasites are left behind in the bath

Tropic Marin® Iod improves the adaptation to light and the colouring of anthozoa, especially of hard corals. Due to its unstable nature in solution, iodine should be added to saltwater aquariums on a regular basis. Tropic Marin® Iod contains iodine in its most effective form, as elementary I2.

• Highly concentrated Lugol’s solution for saltwater aquaria

• Essential trace element for sea dweller

• Exact dosages without prior dissolving

• Improves the adaptation to light and the colouring of anthozoa, especially of hard corals

• Prevents goitre at fish

• Is essential for the hardening of the chitinous shell of crustaceans

• Suitable for an aquarium stocked with marine fish, soft corals, LPS, SPS, other filter feeders and/or crustaceans

• Maximum dosage: Do not exceed a maximum dosage of two drops per 50 US-gal./200 l of aquarium system volume per day.

Tropic Marin® K+ Elements contains a selection of essential cationic trace elements for the promotion of growth and the natural coloring of the corals.

• essential cationic trace elements for corals in liquid form

• together with Tropic Marin® A- Elements, the Tropic Marin® K+ Elements supplies a complete profile of the essential trace elements with only two solutions.

• Tropic Marin® K+ Elements contains predominantly cationic trace elements such as strontium, barium, iron, manganese, copper, zinc, nickel, chrome, cobalt and boron in pure mineral form

• promotes strong growth and the natural colouring of the corals

• no colour loss in the corals from trace element deficiency

• easy to use – suitable for both manual dosage and for dosing pumps

• The dose may be doubled if the corals consume large quantities of trace elements (maximum dosage).
