About This

• CLEARS GREEN WATER WITHOUT CHEMICALS – This 5W UV-C light targets the suspended particles that turn your tank water green and cloudy, restoring water clarity fast without adding treatments that can stress your fish or disrupt your plants. More powerful than 3W units — ideal for tanks up to 50 gallons and low bio-load setups up to 75 gallons.
• SIMPLE SETUP, FLEXIBLE PLACEMENT – Slide on the pre-filter sponge, secure with the included suction cups inside your filter chamber, and plug into any standard outlet. The 9.8 ft power cord reaches easily without an extension cable, and the external on/off switch means you never have to put your hand in the water to turn it on or off.
• WORKS IN FRESHWATER, SALTWATER, SUMPS & SMALL PONDS – Compatible with freshwater fish tanks, saltwater and reef systems, sump filters, small ponds, and hydroponic setups. The 5W output handles higher bio-load environments where a 3W unit may fall short.
• FILTER CHAMBER INSTALLATION REQUIRED – This unit is designed to run inside a filter chamber, sump, top filter box, or external housing — not directly in the main tank. Water must flow through the UV-C chamber for it to work correctly. Not a hang-on or inline unit. Check your filter setup before ordering.
• COMPLETE KIT, BACKED BY OUR TEAM – Every kit includes the 5W UV-C light unit, pre-filter sponge, 2 suction cups, and instruction manual — everything you need right out of the box. Bulb lifespan is 8,000–10,000 hours; replace every 6–12 months depending on daily run time. Questions about setup or compatibility? Reach out and we'll help you get it right.
