PULACO Ceramic Ring Aquarium Filter Media, 1 LB, for fish tank and pond filter

PULACO aquarium filter media arrives as 450 g (1 lb) of ceramic rings packed together in a mesh bag. Each ring measures 0.6 x 0.6 in. The rings are fired from ceramic materials at high temperature and suit freshwater and saltwater aquariums as well as ponds. A bee-like microporous structure gives them a large surface area.

How do you put the ceramic rings into a filter?

The manufacturer directs that the rings go into fish tanks or ponds as filter media. Because the whole pack sits in a mesh bag, the bag can be lifted as one unit and placed in the filter instead of pouring loose rings by hand.

These rings fit water tanks, power filters, hanging filters and various other aquarium filters. Whether the bag is used whole or the rings are emptied out, the ceramic pieces keep the 0.6 x 0.6 in size, so the filter chamber has to have room for that ring size.

Checks before you buy this pack

The pack holds 450 g (1 lb), and every ring measures 0.6 x 0.6 in, so measure the space inside the filter before ordering. A chamber narrower than a single 0.6 in ring leaves no room for the media. Hanging filters, power filters and water tanks are the filter types the manufacturer names for these rings.

The media suits freshwater and saltwater aquariums as well as ponds. Buyers running a tank or pond outside those two water types should check the fit before buying.

What the ceramic rings are made of

The rings are ceramic, fired from their materials at high temperature. That process gives a hard ring that holds its shape as a small cylinder of 0.6 x 0.6 in.

A bee-like microporous structure across the ceramic creates a large surface area on each ring. The porous body is what the maker points to when describing the media, and the mesh bag keeps the full 450 g (1 lb) of rings together for handling.
