5D Nano Bio Balls for Effective Aquarium and Pond Filtration Beschreibung

Fish tank bio balls with nano sized negative ions produce an electrolytic effect on water, making water molecules smaller and penetrating cell membranes to increase cellular activity. Aquarium bio balls are used in fish tanks or aquariums to fully filter and purify the water. This filtration material distinguishes impurities, stabilizes pH and creates a good living environment for fish. It is suitable for top filtration, bottom filtration and external filtration of fish tanks. Condition: New aquarium bio balls do not drop slag or muddy water.
