Tetra Algizit is an anti-algae agent in tablet form with intensive active ingredients and helps immediately with strong algae growth in freshwater aquariums.

Only with healthy and beautiful aquatic plants is an aquarium a visual eye-catcher. Their green often brings out the colour of the fish to their best looking. Without the variety of plants, many aquariums would appear barren, fish would lack hiding places and possibly spawning grounds. Plants not only serve as decorative elements but also take over important biological functions in the aquarium. They enrich the water with oxygen and reduce nitrogen compounds. In addition, there are fish and invertebrates that tirelessly unravel single-celled organisms and algae from the leaves throughout the day. Thus, plants are also settlement area for food. Healthy plant growth depends primarily on three factors: "intact soil" with the right nutrients, sufficient light conditions and good water quality with enough carbon dioxide. The combination of these three factors shows the best results. If one or more of these factors is missing, an imbalance arises, which may be prone to poor plant growth and algae formation.

With Tetra Algizit, stubborn and strong algae problems are immediately slowed down. The tablets contain intensive agents against strong algae growth. This can, so to speak, pull the "emergency brake". Tetra Algizit does not discolour the water. Dead plant and algae residues should be manually removed from the aquarium using a safety net, so as not to alter the water levels. Suspended solids are filtered out.


Tetra Algizit is used according to the enclosed instructions and should be kept out of the reach of children and pets. Algae remedies should generally be used with care. Before use always read the label and the product information.

Oliver Knott recommends:

Thanks to the intensive ingredients Tetra Algizit pulls the "emergency brake" and keeps algae growth low, even stubborn algae will be removed soon!
