Introduction

Breathing bio ring/column is a circular filter media with more rough pore structure,formed through high temperature calcination. This filter is easy to produce eddy current to crush large particulate matter when water flow through it .Breathing bio ring/column main raw material is natural clay, with many rich minerals, such as aluminum, magnesium, iron, sodium, potassium, and calcium.

This filter also with electronegative, can make the filter has very good physical adsorption.When the water PH value partial acid, breathing bio ring/column can slow release the calcium and sodium, effectively prevent the PH reduction, so that to maintain a healthy environment for the fish.
