Production Description
Professional filter material for creating natural ecosystem
The inner and outer walls of the ring are covered with concave and convex pores to reach the internal and external connection channels, provide rich oxygen-containing water flow, and better cultivate nitrifying bacteria.
A variety of non-toxic and pollution-free pure natural materials such as natural fibers, will not release toxic elements for long-term use.
With the addition of tourmaline stone, the ring body changes color when exposed to water, and releases negative ions and trace minerals to absorb and decompose harmful substances.
High temperature firing
Scientific high-temperature firing, not easy to disintegrate after long-term use, and will not release toxins
