There are some lakes that have too many nutrients in them, which could be a big problem for artificial ponds. One of the most important nutrients for algae in water is phosphates, which can be converted to the insoluble mineral apatite using SeDox Speed. This process takes only a few hours and is the best solution for urgent cases where quick relief is needed. SeDox Speed comes in small bags and should be placed in areas with a good flow, such as near a water inlet or in a filter, for the best possible effects. By using SeDox Speed, algae are deprived of the nutrient phosphate, and excessive algae growth is prevented. The effects are effective for up to six weeks, depending on the phosphate content. During this time, the phosphate content of the water is reduced to less than 0.035 mg/l, which is a critical factor for excessive algae growth. The apatite that is formed is not harmful to fish or other living organisms, and is absorbed as a nutrient through the roots of aquatic plants. Algae cannot use apatite for nutrition.
