Main causes of unclear water quality in koi ponds

B: High feeding volume

C: Large gap between the volume of the filtration basin and the proportion of the total water column (i.e., the filtration system is too small)

D: Filter material is aged and not regularly cleaned and replaced

E: No or no germicidal lamps

F: Inferior filter material was used

All of the above can lead to aging or over-fertilizing of the water, or to deterioration of the water quality, which can lead to the growth of bacteria or parasites in the koi pond water. Poor water quality can cause koi to move slowly and poorly as well as get protein worms or other parasites, and if the koi are injured, bacteria can easily take advantage of the situation.

This is usually caused by residual chemicals in the water and the soaking time of the color enhancing feeds, which are not cleaned up in time and can make the koi feel unwell. The water may contain viruses or harmful bacteria which, after a long soak in a drug solution, can become resistant to the drug, and the koi will also become resistant to the drug. The koi will also become resistant to the drug, which means that the drug will be ineffective in the case of this fish disease. Therefore, after treating koi fish disease, theBe sure to adsorb it with activated charcoal in a timely manner.

The main reason is that the organic matter in the water, such as fish feces or residual food, provides a large number of food sources for heterotrophic bacteria, which multiply rapidly and in large quantities. Due to the presence of a large number of heterotrophic bacteria in the water, the concentration of "ammonia", a product of fish metabolism, will also increase, which greatly increases the working capacity of the nitrification system and creates a burden. At the same time, it may inhibit the reproduction of nitrifying bacteria. The gradual accumulation of these ammonia toxins can cause ammonia poisoning and even death of koi fish.That's why some ammonia-absorbing rocks need to be added to the filtration pond.
