There are two different types of U.V. There are U.V. clarifiers that only stop green water problems and U.V. sterlisers such as our Exclusive Aqua Clarity range, which not only eliminate green water, but also kill 99.9% of bad bacteria and viruses that cause fish health problems.
These units are the best on the market and have been proven in both hobbyist's ponds and fish farming. The Aqua Clarity range are engineered using 316L stainless steel which is highly polished on the inside for improved performance.
They utilise high performance germicidal sterilising lamps which still have a radiation level greater than 30,000 micro Watt/Sec/cm2, even after more than 1 year of continuous use. These units also have a lamp life counter and audio visual alarm system to let you know when the bulb needs changing.
The Koi hobby has known about U.V. for over 10 years, but have not accepted the technology until now. The reason is, there is some confusion as to what to expect. A U.V. unit is not meant to replace a bio-filter. You still need a bio-filter for removing the ammonia wastes. You should not expect the U.V. unit to sterilize your pond. There will be bacteria on and in your fish, in the biological filter bed, and on the walls and bottom of the pond. What you can expect is to control harmful bacteria, algae, and other waterborne microorganisms by reducing their numbers. The trick is not to destroy all the organisms in one cycle. But, to expose the unwanted organisms to repeated small doses over a period of time.
If you are serious about koi and want to go along way to helping yourself and your koi to a cleaner more healthier pond then these are a serious prospect .
