About This

• Water Clarity Enhancer: 254nm U-V light helps improve water transparency and maintain water quality, improving water clarity and creating a healthier aquatic environment for fish and plants.
• Submersible & Self-Sinking Design: Built-in weighted base allows the U-V light to sink automatically for effortless setup. IPX8 waterproof construction ensures safe, stable underwater operation in filtration systems.
• Intermittent Use: In winter, run the U-V pond light 2–4 hours daily or every other day. In summer, run it 6–8 hours daily or every other day. If green water suddenly appears, keep it on continuously for 2–3 days, then return to intermittent use. Avoid 24-hour operation to prevent shortening the lamp’s lifespan.
• How to Use: Avoid direct exposure. Whether installed in a large fish tank or a pond, do not shine the light directly at the fish or people. When installed in the fish tank, it should be placed in the top or bottom filter, avoiding the area where the fish swim. When use in pond, do not touch fish directly. Keep in a box or in the filter. Maintain the fluidity of the water. Please use it in the filtration system. Not suitable for acrylic tanks, as U-V may cause material deterioration or cracking.
• Wide Application for Large Water Systems: Ideal for 200 to 2200 gallon systems, including koi ponds, large aquariums, water gardens, swimming pools, spas, and cold plunges. Comes with a 15 ft long power cord for flexible placement.
