I’ve used this ceramic ring filter medium in my 55-gallon freshwater tank for three months. The water clarity has improved significantly, and I notice less ammonia buildup. The rings are durable and fit well in my filter housing. My shrimp are active and healthy, which I attribute to better water quality.

The medium is easy to install and works well with my sponge filter. After a week, I saw visible bacterial growth on the surface. My planted tank has become more stable, and the pH has remained consistent over time.

I switched from a plastic filter medium to this ceramic one in my marine tank. The water flow is more even, and I’ve noticed fewer algae blooms. The hollow design helps distribute water efficiently, which I appreciate.
