    Description

    UV Replacement Tube Globe

    Keep Your Pond Water Clear with a Replacement UV Globe!

    Is your pond water starting to look green or cloudy? Your UV clarifier globe might be due for a replacement!

    The UV Replacement Tube Globe is designed for compatible pond UV clarifiers and sterilisers, helping control free-floating algae that can turn your pond water green.

    UV light works by exposing waterborne microorganisms, including free-floating algae, to ultraviolet radiation as pond water passes through the UV unit. This helps control algae growth and improve water clarity without adding chemical treatments to your pond.

    Available in 8W, 15W, 30W and 55W, these replacement UV tube globes make it easy to maintain your existing UV filtration system.

    Why You'll Love It

    • Helps Control Green Water: UV light targets free-floating algae responsible for green pond water.

    • Improves Water Clarity: Helps maintain clearer pond water when used in a suitable UV filtration system.

    • Chemical-Free Algae Control: Uses ultraviolet light rather than chemical algae treatments.

    • Four Wattage Options: Available in 8W, 15W, 30W and 55W.

    • Ideal for Pond Maintenance: Replace an ageing or faulty UV globe to help restore your clarifier's performance.

    • Supports a Healthier Pond Environment: Helps maintain water clarity as part of a complete pond filtration system.

    • Replacement Component: A practical way to maintain your existing UV unit without replacing the entire system.

    Available Wattages

    Choose the replacement UV globe that matches your existing UV clarifier or steriliser.

    UV Globe Wattage Application
    8 Watt Compatible 8W UV Clarifiers
    15 Watt Compatible 15W UV Clarifiers
    30 Watt Compatible 30W UV Clarifiers
    55 Watt Compatible 55W UV Clarifiers

    Important: Always match the wattage, tube length, fitting and connection type to your existing UV unit before purchasing.

    How Does a UV Replacement Globe Work?

    A UV clarifier is designed to help control free-floating algae in pond water.

    Here's how it works:

    1. Water Enters the UV Unit: Your pond pump circulates water through the UV clarifier.

    2. Water Passes the UV Globe: The UV-C light exposes free-floating algae and other susceptible microorganisms to ultraviolet radiation.

    3. Algae Cells Are Affected: UV exposure damages the cells, helping prevent them from multiplying.

    4. Water Returns to Your Pond: With continued circulation and suitable filtration, green water can gradually become clearer.

    Unlike chemical algae treatments, UV clarification works inside the UV unit without directly treating the entire pond.

    When correctly installed inside a suitable enclosed UV clarifier, the UV light is contained within the unit and does not directly expose your fish or aquatic plants.

    Ideal For

    • Garden ponds

    • Koi ponds

    • Fish ponds

    • Pond UV clarifiers

    • Compatible UV sterilisation systems

    • Controlling green water caused by free-floating algae

    • Routine UV filtration maintenance

    When Should You Replace Your UV Globe?

    UV globes gradually lose their effectiveness over time, even if they still produce visible light.

    If your pond water is becoming green again despite regular filtration and maintenance, it may be time to check your UV globe.

    For best results:

    • Replace your UV globe according to your UV unit manufacturer's recommended service interval.

    • Check that the replacement wattage and fitting match your existing globe.

    • Keep the quartz sleeve clean to allow UV light to pass through effectively.

    • Maintain good water circulation through your UV unit.

    • Ensure your pond's mechanical and biological filtration systems are working correctly.

    Important Information

    • Replacement Globe Only: The complete UV clarifier or steriliser is not included.

    • Check Compatibility: Confirm the wattage, dimensions and connector type before ordering.

    • Never Operate an Exposed UV-C Globe: UV-C radiation can cause serious eye and skin injuries. Only operate the globe inside a properly assembled, enclosed UV unit.

    • Disconnect Power Before Maintenance: Always switch off and unplug the UV system before replacing the globe.

    • Not a Complete Filtration Solution: UV clarification helps control free-floating algae but does not replace mechanical or biological pond filtration.

    • Does Not Remove All Algae: UV clarifiers are primarily designed to control free-floating algae, not algae growing on pond walls, rocks or other surfaces.

    Give Your UV Clarifier a Fresh Start!

    Keeping your pond water clear doesn't always mean replacing your entire filtration system. Sometimes, all you need is a new UV globe!

    The UV Replacement Tube Globe is a practical replacement part for maintaining compatible pond UV clarifiers and helping keep green water under control.

    With 8W, 15W, 30W and 55W options available, you can select the correct globe for your existing UV system.

    Choose your wattage and keep your pond water looking its best!
