Overview
This 28 watt ballast kit is the replacement power supply for the Aquascape UltraKlear 2500 UV Clarifier/Sterilizer (G2). If your UV clarifier has stopped working or the ballast has failed, this kit restores full sterilization and water clarity performance.
What It Does
The ballast powers the UV lamp inside your clarifier. A functioning ballast ensures consistent UV output to eliminate algae, bacteria, and parasites—keeping your pond water crystal clear and fish healthy.
Compatibility
Designed specifically for the UltraKlear 2500 (G2) model. Verify your clarifier model before ordering to ensure proper fit and function.
When You Need It
- UV lamp no longer illuminates

- Ballast has burned out or failed
- Routine maintenance or preventive replacement
Installation
Ballast replacement is straightforward for most pond owners. Disconnect power, remove the old ballast, and install the new one following the included instructions. No special tools required.
