Quartz Germicidal Light
Ultraviolet Clarifiers And Sand Filters. Some Basic Facts
As daylight hours lengthen, the water warms up and free floating single cell algae thrive. This is particularly true when a pond is well filtered. The nitrate content rises and additional food is available for the microscopic plants. The result is an algal bloom and the water turns green.
Ultraviolet clarifiers operating in the germicidal region of the UV light spectrum can be incorporated into koi pond systems to kill the algae and keep green water at bay. The algae are killed when they pass close by the ultraviolet light radiated from the lamp. The dead cells flocculate out and settle on the pond or filter floor.
The UV lamp has a limited usable life of about six months, so change it regularly for the best effect, ideally spring. At the same time, clean the quartz sleeve to ensure maximum efficiency from the lamp. The quartz sleeve separates the lamp from the water flowing past it.
Take care when handling quartz tubes, as they are very brittle and will crack easily. Disconnect the UV unit from the power supply before changing the tube or cleaning the quartz sleeve. Do not switch the unit on again until it is reassembled, because light from the lamp can damage your eyes.
Because UVC designs vary, it is difficult to calculate the size of unit required for a pond. Check the manufacturer’s instructions before making any decisions. These pressure units have been in use in the swimming pool industry for many years. They can be included in a koi pond installation to provide fine polish to the water after it leaves the filter.
To prevent them from blocking, they will need back flushing to waste on a regular basis. This operation usually needs a pressure pump for efficient cleansing. The sand they contain will also need changing from time to time.
