FAQs
How often should I replace the Arcadia UV Bulb?
For optimal performance and to maintain effective algae control, it is recommended to replace the bulb every 9-12 months of continuous use, or as specified by your UVC unit's manufacturer.
Will this bulb kill all types of algae?
This UVC bulb is most effective against free-floating green algae that cause cloudy water. It does not directly address algae that grow on surfaces (like string algae or blanket algae) or dissolved organic compounds.
Can I use this bulb in any UVC sterilizer?
The bulb is designed for compatibility with most ultraviolet clarifiers and sterilizers that accept a 7W PLS UV bulb. Always confirm the specifications of your UVC unit.
How does a UVC bulb clear green water?
The UVC light damages the DNA of suspended algae cells, preventing them from reproducing and causing them to clump together. Your filter can then more easily remove these clumped algae from the water.
Is it safe to look directly at the bulb when it's on?
No, direct exposure to UVC light can be harmful to the eyes and skin. Always ensure the bulb is fully enclosed within its UVC unit before powering it on.
What does '7W PLS' refer to?
'7W' refers to the wattage of the bulb, indicating its power consumption and UVC output. 'PLS' typically refers to the specific type or base fitting of the fluorescent tube.
Troubleshooting
Bulb does not light up
Ensure the UVC unit is properly plugged in and switched on. Check that the bulb is correctly seated in its socket. If the issue persists, the bulb may be faulty and require replacement.
Water remains green after bulb replacement
Verify that the bulb is the correct wattage and type for your UVC unit. Ensure the UVC unit is running continuously. Check if the quartz sleeve is clean; a dirty sleeve can impede UV light. Allow several days for the system to clear the water effectively.
Reduced bulb lifespan
Ensure the bulb is only operated when submerged in water, as specified by the UVC unit's design, to prevent overheating. Avoid frequent on/off cycling, as this can shorten bulb life.

Setup, Compatibility & Care
Compatibility: This 7W PLS UV Bulb is designed to be compatible with most standard ultraviolet clarifiers and sterilizers that accept this bulb type and wattage. Always check your existing UVC unit's specifications before purchasing.
Setup: To install, first ensure the UVC unit is disconnected from power for safety. Carefully remove the old bulb, following the manufacturer's instructions for your specific UVC unit. Insert the new Arcadia UV Bulb, ensuring it is seated correctly. Reassemble the unit and reconnect power.
Care: The primary care requirement is periodic replacement. The UVC output of lamps diminishes over time, typically after 9-12 months of continuous use, even if the bulb still lights up. For optimal performance in maintaining water clarity, it is recommended to replace the bulb annually or according to the UVC unit manufacturer's guidelines. Clean the quartz sleeve surrounding the bulb if accessible and recommended by the UVC unit's manual, as a dirty sleeve can reduce UVC transmission.
