FAQs
How long does the 6W bulb last?
The bulb is rated for over 20,000 hours of use, which translates to more than 2 years of continuous operation.
Does this bulb kill beneficial bacteria?
No, the UVC light only affects water passing directly through the clarifier unit; it does not harm the beneficial bacteria living in your filter media or substrate.
Can I touch the bulb with my bare hands?
It is best to avoid touching the glass directly with oils from your skin; if you do, wipe the bulb clean with a soft cloth or alcohol wipe before installation.
How do I know when to replace the bulb?
The Fluval FX UVC unit has an integrated indicator light that notifies you when the bulb is no longer operational.
Is this lamp suitable for saltwater aquariums?
Yes, it is safe for use in both freshwater and saltwater aquarium environments when used with the compatible Fluval FX UVC In-Line Clarifier.
Troubleshooting
The indicator light is off
Check that the unit is plugged in, the bulb is fully seated in the socket, and the housing cover is properly locked.
Water remains cloudy despite running the lamp
Ensure the flow rate through the UVC unit is within recommended limits and that the quartz sleeve is free of debris or heavy limescale buildup.

Setup, Compatibility & Care
Compatibility
This lamp (MPN: A19990) is exclusively compatible with the Fluval FX UVC In-Line Clarifier. Do not attempt to install this in any other brand or model of UV sterilizer.
Installation
- Disconnect power to the FX UVC unit before starting.
- Unscrew the housing cover and carefully remove the existing lamp.
- Insert the new 6W lamp, ensuring it is seated correctly in the connector.
- Secure the housing, ensuring the O-ring seal is intact to prevent leaks.
Care
When replacing the bulb, it is recommended to inspect the quartz tube for any mineral deposits. While CCFL technology reduces buildup, a simple wipe-down with a soft cloth during the bulb replacement cycle will ensure optimal UV penetration.
