Features 1、[Negative Ions] Filter Media adds nano level negative ion elements, and the addition of highly active negative ion ceramic composite powder in the ceramic ball can form hundreds of millions of pairs of electrodes. 2、[Principle] At the moment when the electrode is in contact with water, the water is electrolyzed, the water molecules become smaller, and it is easy to penetrate the cell membrane to increase cell activity. 3、[Comprehensive Filtration] Mixed filter media can filter and purify water sources in a comprehensive manner, improve water quality, absorb impurities, stabilize PH, and create a good living environment for fish. 4、[Multi Materials] Various filter materials are mixed and can be used in various ways, which not only solves the problem of water quality in aquariums, but also saves time for water changes. 5、[Safe to Use] This fish tank filter ring provides efficient biological filtration to maintain a healthy water environment without compromising water quality.
