Description

Ceramic Rings:-Material:QuartZ.Hollow design effectively distributes water flow and allows massive colonies of beneficial bacteria to grow on and inside each ring, creating an ideal “bio chemical filter”.Their surface area and pores are sized to accommodate bacteria necessary for biological balance and to remove toxic ammonia and nitrite.Great for both fresh and saltwater aquariums.Note: Please,do not change these filter media frequently. After six months of use, change half of them and use new ones with the old ones.The new bio media filter should be washed with fresh water before use and then it is better to put them in boiling water for 20 minutes. If after using it in the fish tank it is necessary to wash the filters, wash them with Aquarium water, do not use tap or boiled water.
