This is a ceramic ring that I designed on Tinkercad, it has a lot of surface area inside and outside which is good for growing beneficial bacteria in your aquarium the beneficial bacteria likes to cling on rough surfaces will and eat up the ammonia that is growing in your fish tank or pond, ammonia is not good for your fish.
