Product Overview
Porous ceramic rings for standard aquarium biological filter media.
Ceramic Rings are one of the most familiar shapes in aquarium biological filter media. The porous ceramic surface provides space for beneficial bacteria to colonize, while the hollow ring shape helps water move through the filter chamber.
The format is simple to handle in media bags, canister baskets, and sump compartments. It also works well beside other ceramic media such as balls, rods, and mixed 3D shapes.
For factory supply, samples can be reviewed by ring style, color tone, pore texture, and finished presentation before the product is added to an aquarium media line.

FAQ
What are Ceramic Rings used for?
They are used as porous ceramic biological filter media in canister filters, sump chambers, internal filter packs, and aquarium refill packs.
Do ceramic rings filter the water by themselves?
The ceramic body provides surface area for beneficial bacteria. Biological filtration comes from the bacteria that colonize the media, not from a chemical reaction inside the ceramic.
How are Ceramic Rings different from Porous Bio Rings?
Ceramic Rings are the standard white hollow ring product. Porous Bio Rings use colored or specialty ring-style pieces for packs that need a different appearance.
Can samples be reviewed before bulk supply?
Yes. Samples can be checked for ring style, color tone, pore texture, and finished presentation before larger factory supply.
