Blagdon 36W Pro UV Clarifier PC for 32,400L Pond
Product overview
This UV light kills the single celled algae and as a result binds it together to form larger clumps. These algae clumps will then be removed from the water by a suitably sized pond filter. To ensure effective algae control the UV lamp must be replaced annually.
Effective long-term control of green water
The Pro UV clarifier is effective for the long-term control of green water by exposing the pond water to ultraviolet (UV) light. It is a chemical free solution with no detrimental effects to the environment or water quality and ensures the destruction of algae and therefore ‘green water.’
To be more precise, the green water algae contained within the pond water is drawn into the UVC via a suitably sized pond pump. The UV lamp, located within a quartz sleeve, allows the UV light to penetrate the pond water as it flows through the casing.
Connecting to your pump
The pump supplying the PRO UVC must not have a pumping head exceeding 20m – 2 Bar. The maximum flow rate recommended is stated in the UVC performance and specification chart. This flow should not be exceeded. The ideal flow rate for your pond is to pump the volume of the pond water through the UVC every 2-4hours. To calculate your pond volume: average length (m) x average width (m) x average depth (m) x 1000 = Litres Pond Volume.
To calculate your pump’s flow rate, fill a container from the outlet hose of the UVC at the pond side. Time how long this takes in seconds e.g. a 10 ltr bucket takes 12 seconds to fill. Divide 3600 (the number of seconds in an hour) by the time it takes to fill the bucket e.g. 12 seconds. Then multiply by the volume of the container. e.g. 10 ltr. Therefore – 3600 ÷ 12 = 300 seconds 300 x 10 ltr = 3000 litres per hour flow rate.
To increase flow you may need to get a larger pump. If flow is too high use an inline valve to reduce it. The purpose of the pump is to transfer green water from the pond to the PRO UVC.
Placing the pump at the opposite end of the pond to the UVC will give the best results.
UVC lamps & quartz sleeve maintenance
The UVC lamp must be replaced every six months / once a season. It is recommended that the lamp
is replaced and reconnected in the spring.
The Quartz sleeve can become coated in lime scale build up in hard water areas. This should be
carefully removed from the quartz sleeve and cleaned with a soft cloth.
A wet test must be carried out after maintenance to ensure there are no leaks before the UVC is
reconnected.

I had pea green pond water for over 9 months and have tried straw bales and other natural products in order to try and combat it. I was at my wits end as nothing worked even though the water sample tests showed all levels were perfect. My only option (other than the use of chemicals) was to try a UV purifier. Best thing I have ever bought, i just wish i had bought it 9 months prior and saved myself a fortune on other products which DO NOT WORK. Within 4 days of setting it up had crystal clear water and can see right to the bottom of the pond and my fish. Highly recommend this product for algae problems, dont waste your time or money on anything else.
Stopped my Algae problem over night
Love it although original replacement bulbs are way over priced
Cleared our pond in a couple of days. Highly recommend this uv filter.
This made a big difference to my pond in less than a week.
Yes it is big and i had to make alot of alterations to my plumbing, but it was worth it.
Really very pleased with the uv excellent service thank you
