We believe that there are 3 major aspects to breeding big, extremely high quality koi: bloodline, food and water. We have tested many methods for creating and maintaining excellent water quality, and came up with the Bakki Shower system and Bacteria House media on our own.

The Bakki Shower helps to break the water down and remove things that aren't needed, and mixes a
bundant oxygen which in turn vitalizes beneficial bacteria to provide biological filtration. We tried to achieve the same results with other media, but were unable to do so.
Bacteria House is made from ceramic and fired in a kiln at 1,300 C. The media is extremely porous which provides ample surface area for bacteria to colonize in. And the far-infrared radiation is very high from bacteria House. Using it in conjunction with the Bakki Shower makes for a excellent bio-filtration system, which requires vert little if any cleaning. All waste is consumed by the bacteria in the filter.

The system should be set up with at least 3 shelves in one set, with the water being
recirculated through the system 2-3 times per hour. Each shelf contains approx. 100 kg of Bacteria House. We use one Bakki Shower set with 300 kg of Bacteria House for our 10 ton ponds. For a 100 ton pond,
we use 4 sets of Bakki Showers with 1.2 tons of Bacteria House media.
We've experienced great results, as have the hobbyists that have adopted our system.
