Replacing your Hozelock UV bulb annually is a great way to help prevent the buildup of harmful green water algae. Renowned for high-quality standards and reliability, a Hozelock UVC works when pond water is pumped through its light rays, exposing any free-flowing algae to high levels of ultraviolet light, inhibiting its growth. You’ll find an extensive Hozelock UV bulb range in our pond equipment collection here at Pond Planet, with a variety of UV bulbs to suit different makes and models. Explore our full range of pond media spares to find replacement equipment and essentials for your pond.
