Aquarium Bio-Ball Filter
These are super bio-balls with a sponge inside! Clarify your water naturally and cultivate beneficial bacteria!
The small size of these bio-balls makes them incredibly versatile and can be added to HOB filters, power filters etc. to gain additional bio filtration capacity.
· Suitable for all fresh water and saltwater aquariums, especially nano tanks.
· These bio-balls are designed to stay in your tank for as long as you need them and don’t need to be replaced unless they are destroyed.
· The bio-sponges inside of the spheres provide more surface area for growth of beneficial bacteria.
· If you do experience excessive buildup on the Bio-Ball, all you need to do is gently rinse it with water from the established aquarium. This ensures the beneficial bacteria will stay on the filter and will still help break down organic materials that get caught inside.
