Water Restrictions and Koi Keeping

Although we are in a drought situation our climate in South Africa has been variable over many years. We have periods of drought and periods of good rains. Do you remember 5 years ago the amount of rain we received? I recall my driveway collapsing where the ground was water logged and the bricks just sunk into the ground. Remember 10 years ago – well the spruit near us was a raging torrent. My koi pond overflowed like a water fall. I had to build diversions at the back of the property to guide rain water way from the pond area that ran into the property from the house next to me. Ponds on the West Rand had so much rainfall that the pH of large ponds was altered significantly. The rain was falling at a low pH of 4.5.
In South Africa we have entered a phase of drought and water restrictions. So what do koi keepers do? We can’t put our heads in the ground and ignore the current situation.

Koi Pond Stocking Densities

In our wonderful hobby – koi keeping – we all tend to fall into a deadly trap, the trap of over stocking our ponds. Koi keepers often keep every koi they buy for as long as possible. Often the quality deteriorates but we still keep them and they keep on growing.

One of the fundamental principles of good koi keeping is good water quality. Look after the water and the water will look after your koi. As we add koi so the pond environment deteriorates as koi are continually feeding and growing. This in turn means that the oxygen is continually extracted from the water and toxic ammonia is added. Consequently the number of koi that can be safely kept in a koi pond (given volume of water) is limited.

It is very important to keep this in mind - each koi needs a minimum amount of water to live a healthy life and grow to its full potential.

Water has a limited koi carrying capacity. The oxygen that is dissolved into pond water being one of the main considerations for life is limited. Further as koi excrete toxic ammonia directly into the water there are limits as to the amount of ammonia koi can tolerate in a given volume of water – even with filtration.

Koi Nutrition

 

About 8 - 10 years ago I really battled to get good growth out of my koi collection. The reason? - The high cost
of koi food. This statement is not pointing finger or sarcasm, but it is an inescapable fact. If you have a large number of koi and you feed them well, it will cost a lot of money. But you will get growth.

Is There a Lighter Side to Koi Keeping?

 

There seems to be only one side to koi keeping - a serious side. The days of fun and humour in the hobby seem to have escaped us. Therefore, I would also like to add to the situation - the HEAVY side of koi keeping or HSOKK for short. We should never take our hobby too lightly. There is a very serious side to koi keeping - long unpronounceable Japanese names, blood lines, future potential and the often used "oh no, no what have you done" look when you describe your filter system to some one who has other ideas. Slapping of the forehead or placing the hands over the mouth or raising the eyebrows whilst whistling between the teeth often accompanies the “ONNWHYD”  - oh,no,no what have you done - look. False teeth can be detected by a gentle rattling that accompanies the whistle. Cavities in the teeth create a melodious soft echo reminiscent of a dolphin’s mating call.
