It installs vertically or horizontally, connects to common pump and tubing sizes, and delivers up to 1,320 gallons per hour of flow. Routine bulb replacement keeps performance consistent across the season.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the CNZ CUV-155 clear green water in ponds and aquariums?\u003c\/h3\u003e\n\u003cp\u003eThe unit passes pond or aquarium water past a UV-C bulb so suspended particles and many free-floating algae cells are exposed to ultraviolet light, which changes their structure and helps them clump or lose viability. Those treated particles are then removed by your filter or settling, returning visibly clearer water.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e55-watt 2G11 UV-C bulb provides continuous UV exposure.\u003c\/li\u003e\n  \u003cli\u003eFlows up to 1,320 gph to match common pump setups.\u003c\/li\u003e\n  \u003cli\u003eWorks with ponds and tanks up to about 4,000 gallons for green-water control.\u003c\/li\u003e\n  \u003cli\u003eRecommended bulb life ~8,000 hours (replace every 6–11 months for best results).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat size and plumbing options are available for installation?\u003c\/h3\u003e\n\u003cp\u003eThe CUV-155 includes fittings for four common tubing and pump outlet sizes so it integrates with many existing pond and filter systems without adapters.
