Koi Pond Equipment – How to Keep the Water Crystal Clear

It is every Koi fish owner’s dream to have healthy Koi swimming in crystal clear water. But how to do that has always been a challenge. There are a few pieces of equipment that will help you in your quest for that elusive perfectly clear water.

The ozone unit is one piece of equipment that you could consider. Aquarium owners have used ozone for some time but it is relatively new to Koi ponds probably because they are very expensive. The ozone is created by passing air through a high voltage electrical discharge. This adds an extra atom to the oxygen. When this is detached it creates a very powerful disinfectant process.

The ozone itself can never be let into the pond. It is very harmful to the fish. But the water is fed through the ozone unit where it is treated before it is returned to the pond. Once treated it is free of bacteria and parasites and has improved clarity.

Another option for improving water quality and clarity is the UV clarifier. These units help to keep the water clear of single-celled algae that flourishes in sunlight and high levels of nitrates and phosphates. The UV clarifier radiates ultraviolet light causing the algae to collapse and decay. This unit is not a UV sterilizer that is commonly used in aquariums.

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.
