Aqua UV Lamp, Sl 100 Watt
AU-A20100
Replacement UVC Lamp for Aqua UV 100W Clarifiers
UV lamp output drops gradually over time. After 14 months of continuous operation, most UV lamps sit at roughly 70% of their original output, often without any visible sign of failure. If green water has returned to a pond that was previously clear, a lamp replacement is the first thing to check. This OEM Aqua UV SL 100W lamp restores full UV output to 100W Aqua UV clarifier models.

When to Replace
Replace annually at spring startup for consistent performance. If green water returns after a previously clear season, replace immediately rather than waiting for the scheduled interval. Output loss is invisible to the eye — the lamp glows but treats at a fraction of its rated capacity.
Installation
Turn off power to the clarifier. Unscrew the twist-cap housing cover. Slide the old lamp straight out. Insert the new SL 100W lamp and reseat the housing cover. Allow the system 1 to 2 minutes to stabilize, then confirm water is flowing through at the correct rate. Handle UV lamps with gloves to avoid skin contact with UVC light during testing.
Ideal for pond owners running Aqua UV 100W clarifier systems who want to restore peak UV output at spring startup or after a green water recurrence.
