Recently a very interesting discussion took place on the Koi4u forum. The discussion centred on the consequences of overstocking and it turned out as a highly emotional topic. The fact remains that the koi keeper creates a far from perfect environment for koi that can never accurately duplicate the natural environment, unless some new technology will enable us to do so. Because water is not an unlimited resource, ponds have to be constructed as a closed system where water is recycled. The hobbyist today can choose between a myriad of filter systems, but in essence the principal behind the systems remain the same. With the exception of perhaps ozone, all utilise bacteria to do the work with varying levels of success. It is also not possible to devise a generic formula to determine the correct stocking levels for all ponds. There are just too many variables that come into play in ponds because of the differences in water volume, surface area, filter system, aeration, turnover rate, feeding regime, water source, water changes, food quality and maintenance schedule by the owner.

This article was compiled by David Hulse and published in Koi Carp Magazine, October 1999. I regard this as the most practical article for the average Koi keeper to understand the buffering of ponds and it is published here with the kind permission of Koi Carp magazine.

The biggest killer of koi is undoubtedly the knock-on effect of unsuitable water quality. Remember, clear water is not necessary healthy water.
Koi is no more than a domesticated carp (Cyprinus carpio). Unlike their wild cousins that are much hardier, koi has been subjected to inbreeding to such an extent that the immune system has been compromised. Koi are therefore much more affected by their environment.
The whole concept of our hobby is not only the ability to keep koi, but the ability to keep the water and pond system healthy. Our systems are based on recycled pond water and during the recycling process; a lot of things happen that has a definite influence on the fish.
