«I could no longer see the fish in my pond and the water had an extremely dark and polluted color. I wanted to tackle this problem and at the same time protect my fish from possible consequences. BIOSTAR® did an excellent job of this, once the main cause, namely high phosphate levels, had been eliminated. Now not only I, but also my fish are extremely happy with the outstanding result.»




Various disruptive factors can occur in the pond, with nitrate and phosphate usually being the main causes. Although they are important nutrients for plants, they unfortunately also promote undesirable algae growth. Therefore, the effective removal of excess phosphate, which is often caused by fish excrement, overfeeding or the decomposition of organic materials, is crucial. Thanks to BIOSTAR® Swampox, we have not only been able to break down the bottom sludge, but also prevent the further formation of sludge.
