The unit pairs a 13-watt UV-C bulb with a vortex flow chamber so every gallon receives multiple passes of germicidal light before returning to the pond. It’s designed to work with a properly sized pump and can be installed inline with existing plumbing or used in combination with mechanical and biological filtration.\u003c\/p\u003e\n\n\u003ch3\u003eHow quickly will I see clearer water?\u003c\/h3\u003e\n\u003cp\u003eThe UltraUV can produce noticeable improvement within 48 hours, depending on algae density and pump flow rate. Because the device destroys free-floating algae as water passes the UV source, clarity increases as more water cycles through the unit.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eVisible reduction in green tint often within two days\u003c\/li\u003e\n  \u003cli\u003eFaster results with correct pump sizing and steady circulation\u003c\/li\u003e\n  \u003cli\u003eRepeated circulation continues to polish water over several weeks\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the vortex chamber improve performance?\u003c\/h3\u003e\n\u003cp\u003eRather than a straight-through path, the UltraUV’s vortex chamber routes incoming water around the bulb multiple times so each volume receives greater UV exposure.
