SERA siporax pond algenstop Professional – biological filter material against algae, 1 kg

Description Unique control of algae in the lake, through bacteriaNutrient-degrading bacteria in a stable, permanent form begin to work and multiply immediately after contact with water and remain active for a long time. They remove algae nutrients – especially phosphates – from the water and thus effectively fight unwanted algae in the garden pond, on the principle of food competition. Algae growth is suppressed and their population is reduced for a long time. Prophylaxis has been made against the so-called algae blooms. It contains bacteria and their breeding ground, which absorb the nutrients of unwanted algae (such as phosphates) and thus count with them biologically, through food competition. The activity of the bacteria decreases after about a month. After one month, the product is not discarded, as it is a highly effective sera siporax filter material, whose life is practically unlimited and it can remain in the filter as a biological filter material.
