Key Features

SILI-OUT 2: Sili-Out 2 removes pollutants such as silicate, phosphate, barium, arsenic, chromium and yellow substances from pond water. The silicate remover is aluminium-based and ideally suited for every pond. A filter bag is included for easy use.

UNHARMFUL FOR ANIMALS: The silicate absorber works in a form that is harmless for animals. The silicate remover has no effect on the pH value in the aquarium.

PROMOTES PLANT GROWTH: By sustainably removing pollutants in the water, Sili-Out 2 promotes the growth of aquarium plants and corals within a very short time in the event of pollutant problems. The growth of unwanted diatoms is prevented.

APPLICATION: Our silicate remover can be used in freshwater aquariums as well as in marine aquariums. To begin with, use 40g of granulate per 100 litres of water. If necessary, the dosage can be increased up to 80g per 100 litres.

ARKA -: Is one of the world's leading brands in biological water treatment. The products are among the most environmentally friendly on the market - the application is safe and harmless.
