Clean and healthy water
Plant and food remains and metabolic substances lead to a deterioration of the quality of the water in the aquarium. Good water quality is necessary for healthy fish and plants. This can be achieved with various filters and filter materials. The filters suck in the aquarium water and remove the pollution and waste materials with the filter material from the water

Clear aquarium water
Replacing the filter sponge regularly ensures clear aquarium water. The water is ideally cleaned thanks to the pore size of 30 ppi. At the same time the sponge promotes the settlement of beneficial cleansing bacteria for an ideal biological filtering
