Description
xOverview
The AA GKM3W Mini Internal UV with Power Head is a compact, submersible UV unit designed for small aquariums up to 20 gallons. Water is drawn through the unit and exposed to the UV lamp as it passes by, offering a streamlined way to help keep the water looking clear and inviting without demanding frequent full water changes.
Why this compact UV unit matters
In tight spaces where you want a clean, low-maintenance setup, this internal UV solution sits inside the tank and uses a dedicated pump to move water through the lamp. The result is a direct contact flow that is simple to monitor and easy to position within your existing filtration layout. The footprint is modest, measuring 2.5 by 2.5 by 7.5 inches, so it integrates into many small to mid-sized tanks without crowding the décor.
- Designed for aquariums up to 20 gallons, making it a practical choice for hobbyists with compact tanks.
- Direct water contact with the UV lamp helps a compact, efficient treatment as water flows through the unit.
Easy installation and reliable operation
Install without tools—simply attach inside the aquarium using the included suction cups. The submersible design houses both the UV bulb and the pump, staying out of sight while keeping the unit secured in place. The LED indicator clearly signals when a bulb replacement is needed, making routine maintenance more predictable.
- No tools required for placement and setup.
- Submersible design with suction cups for quick, secure mounting inside the tank.
- LED indicators help you monitor bulb status at a glance.
