Biological Media

Effective biological filtration is incredibly important for a healthy underwater ecosystem. This is where bio balls come in. Aquariums and ponds need beneficial bacteria to grow and balance out any harmful debris in the water. Bio balls are designed in a very specific way to increase the surface area that good bacteria can cling to. The large surface area of the bio balls is down the ridges and crevices that you can see all over them. This gives good bacteria more places to settle; if there is more space for this good bacteria to grow, there will be better biological filtration.

You will need to choose your mechanical filter media first, to ensure that superficial waste is removed effectively. Bio balls do not remove large pieces of decay in the aquarium, but filter out small particles and reduce the production of harmful chemicals like ammonia. Having a mechanical filter media system in place helps bio balls to do their job more effectively. Find out more about pond and aquarium filtration.
