Reliable, compact UV-C sterilizer for ponds and aquariums. This Classic 25W model with 3/4" ports adds a manual wiper to help keep the quartz sleeve clear between services—great for polishing loops, QT systems, and modest displays.
Classic housing with 3/4" inlet/outlet for easy inline plumbing
Single low-pressure 25W UV-C lamp for algae/bacteria/protozoa control
Integrated manual wiper helps maintain sleeve clarity and consistent UV output
Weather-resistant (non-submersible) body for indoor or protected outdoor installs
Clear end cap shows lamp-on status; quick access for lamp/sleeve changes
Note: Wipers are not recommended for saltwater use; using a wiper on saltwater can void the wiper warranty. Many marine installs choose the non-wiper variant and clean the sleeve during lamp changes.
