How They Work

The bacteria that colonise the rings are what complete the Nitrogen Cycle in your filter. As water passes through the filter, these bacteria help convert harmful ammonia and nitrite into less harmful nitrate. The more surface area the media offers, the more room there is for these bacteria to establish. That is why ceramic rings are a popular choice for the biological stage of a filter.

Frequently Asked Questions

What are ceramic rings used for in a filter?
They are biological media. Their large surface area lets beneficial bacteria grow, and those bacteria help convert ammonia and nitrite into less harmful nitrate.

Can I use them in both a pond and an aquarium?
Yes. They are designed for pond and aquarium use.

Do the rings crumble over time?
They are described as non-crumbling, so they are made to hold their shape in your filter.

Do the rings remove ammonia on their own?
The bacteria that grow on the rings do the work. The rings provide the surface area those bacteria live on, and the bacteria carry out the conversion of ammonia and nitrite to nitrate.
