Cleansing method that makes maximum use of "fermentation" mechanism based on aerobic bacteria and porous stones.
When effective bacteria come in contact with water, they start propagation in the porous stones and disperse outside of the block. Organic matter is sucked in by the EBB Bacteria, settles, and decomposes, clarifying the water. Because necessary nutrients are encased in the block, Eco-Bio Block remains effective for a long period of time.

←Eco-Bio Ring Testing
The water has never been changed since October 2001.
Only add the same amount of water which has vaporized.
※The Eco-Bio Ring has been changed a few times because it runs out in about 2 years.
The Eco-Bio block for the river is a joint development commodity with Koyoh Co., Ltd.
