Maintain the clarity and performance of your Aquascape UltraKlear® 1000 UV Clarifier with the Aquascape 14-Watt High-Output UV Replacement Bulb (95039). This authentic replacement is designed specifically for use with the UltraKlear® 1000 system (Model 95036), which is manufactured under EPA Establishment Number 90462-CHN-1. UV bulbs naturally degrade in effectiveness over time—especially after a full pond season—so annual replacement is recommended to maintain peak UV output. Even if the bulb still illuminates, its ability to perform properly diminishes. This 14-watt high-output bulb installs in minutes with no tools required, making it a simple and reliable maintenance task for both pond contractors and homeowners. Backed by Aquascape’s 30+ years of leadership in the pond industry, this replacement bulb is built for performance, durability, and compatibility. Trusted by koi keepers, fish pond owners, and professional installers, Aquascape parts deliver peace of mind and long-term value.
