The phosphate in aquaria derives from fish excrement and the decomposition of inorganic substances (dead plant matter, food residues, sludge, etc.). In the concentration which normally applies in aquaria, phosphate is harmless to fish and represents one of the main nutrients for aquarium plants. The problem arises from the fact that phosphate is also one of the most important nutrients for algae. While most aquarium plants thrive on even the most minimal phosphate concentrations (0.01 - 0.1 mg/l), troublesome algae have a taste for as much phosphate as possible. Higher phosphate levels (over 0.5 mg/l) thus often lead to severe algae problems.
In an aquarium which is set up and maintained in accordance with the Dennerle system, with a well-balanced stock of fish and plants, phosphate will not normally become a problem. Phosphate only accumulates in higher concentrations when an imbalance applies between nutrient input (too much food, too many fish) and nutrient consumption (too few plants, infrequent water-changing). In such cases, Dennerle PhosphateStop Supra helps to restore the necessary balance to the aquarium. It deprives algae of one of its main nutrients. Excessive algae growth is effectively checked and generally comes to a standstill within a few weeks.
Dennerle PhosphateStop Supra binds the phosphate which is dissolved in the aquarium water and converts it into a waterinsoluble form. Even when its binding capacity is exhausted, it does not release the bound phosphate again. PhosphateStop Supra is highly effective and requires little space in the filter – no negative effect on the bio-filters performance. The contents of one pack are able to bind up to 24,000 mg of phosphate. PhosphateStop Supra is pH-neutral, does not release any harmful substances and is thus excellently tolerated by fish and plants.
Application: use Dennerle PhosphateStop Supra between 2 layers of fine filtering wool in the final position in the filter. The package content is sufficient for 250 l aquarium water. Incl. Dosing spoon and filter net bag.Do you have questions about this article ?
