Creating and maintaining optimum water conditions in marine aquariums

Product description

Tropic Marin® Pro-Tect improves the quality of the water – especially in fish aquariums – through a combination of highly efficient active ingredients. The welfare of the animals is improved.

The protective colloids it contains protect the sensitive mucous membranes of the fish against pollutants and also promote regeneration. Toxic heavy metal ions are bound and therefore neutralised. The stabilisation of the pH-value reduces stress for the animals. The greater effectiveness of the protein skimmer successfully frees the water from turbidity and organic impurities. The active ingredients are supported by a selection of essential trace elements to prevent any deficiency of these important minerals.
