Without beneficial bacteria in the tank, her fish will die. The whole allude of ceramic rings is to residence these useful bacteria, thus enabling for proper biological filtration, and also ultimately the survival of her fish.

2. Denitrifying Bacteria

Something to note about ceramic ring is that they are usually considered far better than other develops of organic filtration media.

The factor for this is due to the fact that ceramic rings can house two different types of bacteria, these gift nitrifying and denitrifying.

Many varieties of bio media can only hold nitrifying bacteria, which turn ammonia into nitrite.

However, that nitrite is quiet harmful to fish and also needs to be broken down further, into nitrate.

Denitrifying bacteria turn nitrite right into nitrate, and this is necessary for a fish tank. Therefore, ceramic rings are very great because they have the right to house both that these types of bacteria.
