In ponds with a high phosphate content, when there is a continuous supply of nutrients (e.g. from contaminated water, fish population, etc.) and/or with excessive sludge sediment.
SeDox converts phosphate, the most important nutrient for algae in water, to the insoluble mineral apatite, thus depriving the algae of the nutrient phosphate. SeDox is effective for at least six weeks. During this time,
it reduces the phosphate content of the water to less than 0.035 mg/l, the critical factor for algae growth. SeDox also facilitates the decomposition of sludge in ornamental ponds and biotopes, preventing sludge from
forming quickly. The apatite that is formed is not harmful to fish or other living organisms. It is absorbed as a nutrient through the roots of aquatic plants (with the exception of algae).
Ideal application time
SeDox is most effective before and after the winter, because this is when the concentration of nutrients in the pond water is highest. It is essential to administer SeDox in the spring, because the phosphate concentration,
which causes algae to grow, increases in the winter. SeDox is also effective at very low water temperatures. When a substantial amount of the water is replaced or water is added to the pond, SeDox should be added;
tap water often contains a high concentration of phosphate. When algae bloom is excessive, SeDox should be administered before or several days after AlgoClear/AlgoLon, because the dying algae releases nutrients
into the water and SeDox can bond the nutrients.
Type of application
Spread SeDox evenly over the surface of the pond without first diluting it in water. Rinse powder residue off of plants. The filters can remain in operation, and animals can remain in the pond during treatment with
SeDox. SeDox works for 6 – 8 weeks and should not be removed from the pond during this time. Otherwise the phosphate concentration can not be reduced to less than 0.035 mg/l. Do not use robots or other ground
cleaning equipment during this time! If a stream flows into the pond, SeDox should also be sprinkled into the stream.
30 g SeDox per 1000 liters (1 m³) of pond water.
If the phosphate level is elevated year round due to external factors (fish feed, surface water high in nutrients, dead leaves, etc.), SeDox should be used all year (every eight weeks, because this is how long it remains
active in the water).
SeDox should not be administered if the pH-value of the water is greater than 8.8! In this case, the water should be pre-treated with pH-Minus and then OptiLake, products from the Lavaris Lake pond care program.
Ponds with sturgeon: SeDox may be used only in places that the sturgeons do not go and do not eat, e.g. in the preliminary filter zone. An ingredient in the product could be harmful when ingested by sturgeon.
SeDox is available in the following quantities: 1 kg, 2.5 kg, 5 kg, 10 kg, 25 kg, 50 kg.
Please store in a cool, dry place, protected from frost. Keep out of reach of children!
