AS 2.0 9W UV steriliser

This 9 W UV-C sterilizer is for aquarium keepers with 400-600 L tanks who want to reduce free-floating microorganisms in the water column while keeping their existing filtration. It mounts on filter hoses of two common diameters or can be placed fully underwater, so it suits both external filter setups and tanks where space is limited.

Why it matters

• Two hose sizes are supported (12/16 mm and 19/25 mm), so the unit can be connected to most external filter lines without adapters, provided the hose falls within these diameters.
• The housing is rated IPX8, which the manufacturer states allows operation while fully submerged.
• The UV-C lamp switches off automatically when the housing is opened, which reduces exposure to UV radiation during maintenance.
• The lamp is rated for up to 10,000 hours of operation. The manufacturer recommends replacement roughly every five years, and the electronic ballast is stated to cut energy consumption by 50% compared with conventional designs.

What it works with

The sterilizer is intended for aquariums in the 400-600 L range and works with external filtration that uses 12/16 mm or 19/25 mm hoses. Because the rated flow is up to 1000 L/h, the water should pass through the unit at or below that rate for the intended exposure. Check the hose diameter and flow of your existing filter before purchase.
