Do I Need Bio Balls in My Filter?

Bio balls are used to hold the beneficial bacteria from your tank and not for removing waste products from the system. We recommend that these are used after the water flows through filter foam as the foam will catch and remove any debris from the water meaning these will not get stuck in the groves of the Bio balls.

Do I need bio media in my filter?

Biological Filtration

Without the bacteria, fish would immediately be poisoned by the presence of ammonia in the water. In an aquarium, hobbyists can supply special biological filter media (bio-media) which simply provides extra surface area for the beneficial bacteria to grow.

Are bio rings necessary?

Bio-Rings are just ceramic rings that provide a home for the nitrifying bacteria. They aren't needed, but loosing them would reduce the amount of bioload your tank can handle.
