FAQs
How often should I replace my Yamitsu 55w UV bulb?
We recommend replacing the bulb once every 12 months, ideally in early spring, to ensure maximum algae-clearing performance.
Does this bulb fit all Kockney Koi units?
No, this is specific to 55w units. Always check the wattage requirement of your specific Algae Master unit before purchasing.
Why does the bulb appear to be on, but the water is still green?
UV bulbs lose their germicidal effectiveness before they actually burn out. Even if it glows, the UV output may be too weak to kill algae.
Can I touch the bulb with my fingers?
It is best to avoid touching the glass directly. Skin oils can cause uneven heating and premature failure of the bulb.
Is this bulb compatible with other brands of UVC units?
It is compatible with many standard units that use a double-ended 55w 90cm tube, but you should confirm the pin configuration and length requirements of your specific housing.
Troubleshooting
Bulb does not light up after installation
Verify that the pins are fully seated in the socket and check that your UVC unit's ballast or power supply is functioning correctly.
Water remains green despite new bulb
Check the quartz sleeve for heavy scale buildup, ensure the flow rate of your pump isn't too fast for the UVC unit, and verify that the water is passing through the chamber correctly.
Bulb flickers
This often indicates a loose connection at the pins or an aging ballast within your UVC housing.
Pros and Cons
Pros

- Compatible with widely-used Kockney Koi Algae Master systems
- Standardized pin connections simplify the replacement process
- Reliable performance for seasonal pond maintenance
Cons
- Requires annual replacement for optimal UV efficacy
- Glass tube is fragile and requires careful handling during installation
- Physical length of 90cm is not compatible with smaller 18w or 36w units
Setup, Compatibility & Care
To install the bulb, first ensure the power to your UVC unit is completely disconnected. Carefully slide the bulb into the quartz sleeve, ensuring the pins on both ends align perfectly with the electrical sockets. Never touch the glass surface of the new UV bulb with bare skin, as natural oils can create hot spots that shorten the bulb's lifespan; use a clean, dry cloth or gloves during handling. To maintain the bulb's effectiveness, clean the surrounding quartz sleeve periodically to remove limescale or debris buildup that might block UV light transmission. Always replace the bulb once a year, even if the light appears to be working, as the UV radiation output degrades significantly after about 6,000 to 8,000 hours of use.
