The very water we drink, is not fit for Koi by any means.

Mains water contains Chlorine and many hard metals, that just simply are not healthy, or productive for a healthy and balanced nitrogen cycle. The water purifiers we offer are suited to the task of protecting our Koi from the harmful elements within our public water systems. They are, naturally, not intended for use as drinking water purifiers for human consumption.


To have effective water purification it is best to allow for very slow flow rates. The longer the water takes to pass through the purifier, the greater the benefits of the purification system. A flow rate of one to two gallons per minute should adequately remove any nasty impurities, and the water can safely be added directly into your filtration system or the pond.

Koi-keepers need to take great care to ensure that none of this compound reaches the pond as it can destroy the filter balance and seriously damage fish health.

Various media have been promoted to deal with Chloramine but all have suffered from limited effectiveness over any length of “life”.

The Cartridges can also be used to upgrade all other makes using the standard 4.5 inch Dia x 10” housings to an effective performance.
