Bio-UV Replacement Bulbs

UV replacement bulb / lamp for pond UV clarifier maintenance

Bio-UV Replacement Bulbs is a pond UV spare designed to help keep a compatible UV clarifier working efficiently. UV systems rely on a clean quartz sleeve and a strong lamp output, so keeping the correct spare parts available is important for reliable green water control and clear pond water.

Before ordering, check the model number, wattage, existing lamp type and any manufacturer part code on your current UV unit. Some UV bulbs can look similar while using different pin arrangements, lengths or sleeves, so matching the spare to the exact UV model is always the safest option.

Fitting advice

UV spares are simple items, but they are important because a tired lamp or dirty sleeve can make a UV unit look as though it is working while the effective UV output has dropped. Replacing the lamp at the right time and keeping the sleeve clean helps the pond filter remove algae more easily and keeps the UV system doing the job it was bought for.

• Switch off and isolate the UV unit before servicing.
• Allow the unit to cool before removing the lamp.
• Handle quartz sleeves carefully, as small cracks can cause leaks.
• Replace seals or O-rings if the manufacturer recommends doing so.
• Confirm that the unit is watertight before switching the UV back on.
• Do not touch the glass of a new UV lamp with bare hands if the manufacturer advises against it.
• Clean limescale from quartz sleeves carefully so the UV light can pass through properly.

Before you order

If you are unsure which spare you need, compare the wattage, brand, model name and existing lamp code before ordering. A UV bulb with the correct wattage can still be wrong if the pin layout or length is different, so the safest approach is to match the replacement to the original unit rather than relying on wattage alone.

If the UV has stopped clearing green water, replacing the lamp and cleaning the sleeve is usually the first service check before assuming the whole unit has failed.
