Tetra PhosphateMinus reliably removes excessive phosphate (PO4) from the aquarium water. Phosphate continuously accumulates in the aquarium water through the decomposition of organic substances such as fish faeces, food and plant residues. This is a natural process in the aquarium. However, the condition of the tap water used also affects the PO4 value. Phosphate is essential for aquarium inhabitants and plants, as it is needed for many biochemical processes such as photosynthesis. However, too much phosphate in the aquarium (above 2 mg/l) promotes the growth of undesirable plants. In addition, excessive levels of this nutrient can affect water quality. Therefore, the PO4 level should be as low as possible (below 2 mg/l). Tetra PhosphateMinus gently and reliably removes excessive phosphate from the water (up to 2 mg/l when the recommended dosage is observed). A major advantage of this product is that it does not cause turbidity or deterioration of the aquarium water or deposits on the substrate. Its active ingredient - an organic iron compound - decomposes slowly and naturally. Within only 48 hours, the product is biodegraded in the aquarium by microorganisms and can be absorbed and removed by the aquarium's filter together with the remaining phosphate residues. The filter must therefore be cleaned regularly to completely remove the degraded phosphate from the ecosystem. Tetra PhosphateMinus reliably lowers the PO4 value without affecting the carbonate hardness (KH). For this reason, the product is also suitable for aquariums with soft water. This makes Tetra PhosphateMinus a reliable and safe care product for all aquarium inhabitants.
- Reliably reduces high phosphate levels
- Acts particularly gently and naturally thanks to the micro-organisms in the aquarium
- Gentle and harmless for all aquarium inhabitants
- Does not cloud the water and leaves no deposits on the substrate
- Suitable for soft water (no minimum carbonate hardness required)
- Too high a phosphate content promotes undesirable plant growth
The orientation of Tetra (founded in 1951), one of the most traditional and at the same time most innovative companies in the landscape of German aquaristics, goes far beyond the production of feed for aquarium inhabitants. The perfect interplay of research and quality ensures the highest grades, even according to the IFS standards. Beside of the well known TetraMin or the popular water care products, Tetra offers complete aquarium sets and modern cabinets in 120 countries around the globe. Tetra has been shaping and influencing the modern world of aquaristics for over 70 years with its innovative strength like hardly any other company.
