CUV‑505 – 5W UV-C lamp

This UV-C sterilizer is intended for aquarists who have algae blooms or cloudy water, or who want to reduce pathogens in a fish tank of 150–800 L. It is designed to be fitted on the outlet hose of a canister filter, so the water passes through the UV chamber before returning to the aquarium.

Why it matters

• Hose fitting: the unit accepts 16, 20 and 25 mm hoses, which covers the most common canister filter outlets.
• Flow: the inlet, outlet, bulb and housing sit in one straight line, so the lamp adds no restriction to the flow and does not overload the filter or pump.
• Inlet protection: a bell-shaped inlet with fine perforations and a supplied strainer keep fish, shrimp, plants and debris out of the chamber.
• Compact layout: the small dimensions allow installation inside an aquarium cabinet.

What it works with

The sterilizer is suited to freshwater and marine aquariums in the 150–800 L range that run on a canister filter with a hose outlet. The kit includes connectors that allow the unit to be used as an internal filter with SunSun HJ series pumps. Pair it with a pump whose flow matches the aquarium volume, as the lamp does not change the pump's rated output.
