How to Change the 9w UV Bulb on Inpond 6000/9000

Your Blagdon Inpond 5in1 6000 or 6in1 9000 includes a 9w UV Green Water Clarifier to maintain crystal clear and healthy water all year round. The UVC helps to clear green water caused by suspended green algae. The UV light damages single celled algae so it can be removed by the Inpond filter. To ensure your UVC runs effectively when needed most, we would advise replacing the UV bulb every spring.
