What are Ceramic Rings Used for in your Aquarium?

This beneficial bacteria removes ammonia and nitrites (harmful chemicals) from your aquarium. These chemicals naturally build up inside your aquarium, and if the bacteria in your tank don’t remove them, then your fish will eventually die. As you see, these beneficial bacteria are pretty important.

Ceramic Rings

Well, these bacteria need a place to live. Ceramic rings offer the perfect home for the beneficial bacteria in your aquarium.

You see, beneficial bacteria need a surface to cling to. The more surface that is available, the more bacteria that your filter media can hold.

Ceramic Rings increase their surface area through tiny little pores. These pores are so small that you can hardly see them without a microscope…

However, ceramic rings have an additional advantage over other types of filter media…

Ceramic rings can hold a second beneficial bacteria:

Denitrifying bacteria.

These bacteria eat nitrates and will only survive where there is no oxygen present.

Denitrifying bacteria live deep inside rock, ceramic and other porous materials, where oxygen cannot reach them. You won’t find this bacteria in plastic or foam filter media.

However, just because denitrifying bacteria help to combat nitrates, it doesn’t mean that you can skip water changes.
