The unit uses a 254nm U-V wavelength, a dual-tube design with a larger 42mm glass sleeve, and an IPX8-rated waterproof housing to operate reliably in filtration chambers. It’s built to run intermittently for seasonal control and includes a weighted, self-sinking end for easy placement inside a filter or sump.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this unit clear green water and reduce algae?\u003c\/h3\u003e\n\u003cp\u003eThe hygger 32W uses ultraviolet light to inactivate free-floating algae and microscopic organisms that cause cloudy, green water. Installed in the filter or sump, water passes through the U-V chamber where exposure disrupts algal cells, helping particles clump and be removed by your mechanical\/biological filtration.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e254nm U-V wavelength targets free-floating algae and microbes.\u003c\/li\u003e\n  \u003cli\u003eDual-tube configuration doubles exposure area for higher throughput.\u003c\/li\u003e\n  \u003cli\u003e42mm glass sleeve offers greater water contact time than thinner tubes.\u003c\/li\u003e\n  \u003cli\u003eBest used inline in a filter chamber—keeps lamp away from fish and swimmers.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhere and how should I install the hygger 32W U-V light?\u003c\/h3\u003e\n\u003cp\u003eInstall the unit inside a bottom filter tank, sump or dedicated U-V chamber—do not place it directly in the display tank.
