Power rating: 5 Watts
Compatibility: Designed for Fil 250 + UV and 400 + UV aquarium filters
Included components: UV-C lamp and sealing ring
Application: Freshwater and marine aquariums
How to use
Before performing any maintenance, ensure that the aquarium filter and the UV-C unit are fully disconnected from the electrical power supply to prevent electric shock and eye damage. Open the filter housing according to the manufacturer instructions, carefully remove the exhausted lamp, and replace it with the new sera UV-C lamp, making sure to install the provided sealing ring correctly to ensure a secure seal. Reassemble the unit, check for any potential leaks, and reconnect the power supply only after the installation is fully secured.
What to consider before purchase
Verify your existing filter model to ensure it matches Fil 250 + UV or 400 + UV
Confirm that a 5 W power specification meets your aquarium maintenance requirements
Check the replacement schedule of your current UV-C lamp to ensure it is time for a new unit
Usage recommendations: Always handle the quartz glass of the UV-C lamp with a clean cloth or gloves to avoid leaving skin oils, which can reduce the lamp's operational lifespan and efficiency. Replace the lamp approximately once a year to maintain consistent performance in controlling algae and microorganisms.
