If you have chlorine or chloramine treated water, K.O.I. has always recommended the use of a water shut off timer whenever doing a pond refill. In fact, they are so cheap (and they do sometimes fail, that Spike now recommends using 2 of them, one after the other.
But there is another way that doesn't involve the use of ANY device. Read what the Fish Vet in Australia recommends.
This study evaluates the toxic residual pharmaceuticals in the water as they affect algae, the environment and fish. The results indicate that there are numerous other external factors that complicate the testing. An interesting study, not directly related to our Koi, but certainly affecting our water sources. The list of chemicals they tested for is staggering!
This study examines the effects of nitrite poisoning, and how to prevent it. As a further benefit, the study examines the carp's ability to recover. This is something every Koi keeper needs to know, as it will be useful each time a filter is 'started.'
While it is winter here, it is the hottest part of the summer in Australia, and drought combined with high temperatures is killing thousands of fish in the NSW rivers. What is actually killing the fish?
This brief article by Syd Mitchell explains the part that plants play in the Nitrogen Cycle.
Pollution of the aquatic environment by sodium fluoride from some industrial processes has been linked to delayed hatching of fish eggs and reduced growth, which is why, when I clean my teeth, I rinse my mouth into the sink, not my Koi pond.
Manufacturers of products such as these do not like to divulge their trade secrets, so it is difficult to determine the exact make-up without expensive laboratory analysis.
Below is the text of a recent study that evaluated the use of Vitamin C to de-chlorinate water. They found it much cheaper and more effective than many other chemical solutions. This study was done for municipal water systems, but has direct benefits for Koi ponds as well! Full methodology, as well as recommended dosages are given. There are additional benefits to using Vitamin C as well.
