Sui Jin Sludge Free for a Clear Pond

German packaging: SchlammFrei

Soil deposits from fish droppings, leaves, food etc. often cause excess nutrient formation in the sludge and thus trigger the dreaded algae bloom - the pond water turns green and becomes cloudy. A lack of oxygen is often the main reason why the natural breakdown of such by-products no longer works efficiently. The solution? External introduction of oxygen into the substrate!

SchlammFrei or Sludge Free by SUI JIN reduces sludge formation and thus prevents excess nutrient formation. It works on a purely biological basis with bacteria and active oxygen as the active ingredients.

How to use: sprinkle evenly over the pond surface, if possible also ventilate the pond system, this accelerates the local breakdown of sludge. The granulate works most effectively at a water temperature of over 15°C. Colder water reduces bacterial activity and sludge reduction takes more time.

Dosage: When using for the first time, 30 ml per 1,000 litres of pond water should be sprinkled. For optimal and sustainable results, a weekly application of 10 to 20 ml per 1,000 litres of pond water should start about 30 days after the first application.
