Product Information
Full details
The Yamitsu 25w Pond UV Bulb is an essential replacement component for pond owners utilizing Kockney Koi Algae Master systems or any UVC unit requiring a standard 25w double-ended lamp. Designed to neutralize suspended algae, this bulb ensures your pond water remains clear throughout the peak season. While it offers reliable performance, pond owners must note that UV intensity naturally degrades over time, necessitating an annual replacement schedule to maintain effective filtration efficiency.

FAQs
How often should I replace my UV bulb?
It is recommended to replace the bulb annually, ideally in the spring before peak pond season starts.
Will this bulb fit non-Yamitsu brands?
Yes, as long as your unit requires a 25w double-ended tube with a 25mm diameter and dual-pin connections.
Does the bulb kill beneficial bacteria?
No, the UV light only affects algae and pathogens passing directly through the UVC chamber; it does not harm the bacteria living in your biological filter.
Can I touch the bulb with my bare hands?
It is best to avoid this, as oils from your skin can cause the bulb to overheat or fail prematurely.
Why is my new bulb not working?
Verify that the bulb is fully pushed into the socket and that the quartz sleeve is not cracked or leaking.
Troubleshooting
Bulb does not light up
Check that the two-pin connectors are fully seated and that your power source is active.
Pond remains green despite new bulb
Check the quartz sleeve for mineral deposits or lime scale; a dirty sleeve blocks UV rays from reaching the water.
Bulb flickers
Ensure the ballast in your UVC unit is functioning correctly and all electrical connections are dry and free of corrosion.

Setup, Compatibility & Care
Before handling the new bulb, ensure the UVC unit is disconnected from the power supply. When installing, avoid touching the glass directly with your fingers, as oils from your skin can create hot spots that shorten the bulb's lifespan; use a clean, dry cloth to handle it.
- Turn off the pond pump and UVC power supply.
- Carefully unscrew the end caps of the UVC unit.
- Remove the old bulb and slide the new Yamitsu 25w bulb into the quartz sleeve.
- Secure the two-pin connections firmly into the sockets.
- Replace the end caps and ensure all O-rings are seated correctly to prevent water leaks.
- Power on the system and check for proper operation.
