Koi Pond Equipment - How to Keep the Water Crystal Clear
Friday, August 14th, 2009Every Koi owner wants to have their fish swimming in crystal clear water. But exactly what do you have to do to get the water in a Koi pond that clear and how do you keep it clear? There are a few pieces of equipment that you might consider trying in your Koi pond.
Consider the ozone unit. Aquarium owners have used ozone for some time but it is relatively new for Koi pond owners. The ozone is created by passing oxygen through a high voltage electrical discharge. This adds an extra atom to the oxygen molecule. This extra atom is detached and creates a powerful disinfectant effect in the process.
Clearly ozone is dangerous for the Koi and can never be allowed in the pond. In using this equipment water is fed into the ozone unit and treated. It is then returned to the pond free of disease, bacteria and parasites and with improved water clarity. Unfortunately these systems are very expensive and out of the reach of most owners. But they are something that should be investigated and may be added as you can afford them.
Another less expensive alternative for improving water quality is the UV clarifier. These units remove single-celled algae that flourish in sunshine and in high levels of phosphates and nitrates. The water is passed the clarifier where the ultraviolet light destroys the algae. These are less expensive alternatives to the ozone unit but they are not substitutes. They do different things to improve water clarity.
This unit is also different from the UV sterilizer that is often used in aquariums. The clarifier allows a higher volume of water to pass over the ultraviolet light. The sterilizer lets less water pass closer to the light for a higher dose.
You can add a variety of “water polishing” units to your filtration system to greatly improve the water quality. This has commonly been accomplished by passing the water through a sand filter as the last stage before the water is returned to the pond. Today there is even a more cost effective way to do this using a canister device containing a series of sieve plates to filter out extremely fine particles.
Consider these options as you look for ways to get that extra water clarity in you pond. It will make a real difference and greatly enhance the enjoyment you get from your fish.
