Important Coral Nutrients:  Amino Acids and Nitrogen Compounds




Product description

Stimulates coral growth, intensifies colouring and reduces phosphate in the reef aquarium biologically.

Pale or brownish corals are often caused by too weak a concentration of easily digestible nitrogen compounds. Tropic Marin® Amino-Organic contains amino acids and other organic nitrogen compounds that stimulate the growth of soft and hard corals, as well as disc anemones and zoanthids. This results in greater absorption, by the anthozoans, of the phosphate available from the water, biologically reducing phosphate concentrations.  These near-natural conditions result in the anthozoans opening better, visibly flourishing, with greater vitality and a more intense colouring. Tropic Marin® Amino-Organic does not contain nitrates or phosphates.

  • biologically reduces elevated phosphate concentrations

  • stimulates coral growth

  • corals thrive with greater vitality and exhibit improved colouring

  • increased opening of the polyps of anthozoans

  • nitrates and phosphates free

Application & Dosage

Add a maximum of 5 ml (0.17 fl. oz.) Tropic Marin® Amino-Organic to 200 litres (52 gallons) of aquarium water daily.

Do not use with phosphate concentrations below 0.03 mg/l, during the start-up phase of the aquarium, or in the presence of undesired dinoflagellates!

Oxidising filters, such as trickle filters, canister filters and bio filters, can reduce the effectiveness of Tropic Marin® Amino-Organic. If a slight increase in nitrate levels is observed, this may be the cause and is generally harmless.

As well as nitrogen compounds, trace elements are also important for good colour definition. We therefore recommend that you also add Tropic Marin® K+ and A- Elements.
