Designed with heavy-duty quartz glass, multi-level seals, and an integrated gravity block for stable underwater placement, the unit connects with a 17-foot cord for flexible positioning. It is intended for periodic daily use and for installation where water passes directly across the lamp for best performance.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this UV light reduce green water and odors?\u003c\/h3\u003e\n\u003cp\u003eThe unit emits UV-C energy that disrupts cellular structures in suspended algae and other microorganisms, which helps clear cloudy green water and reduce smell caused by organic activity. It does not chemically treat water; instead it inactivates organisms while they pass the lamp's irradiation zone.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e100-watt UV-C output for high-intensity exposure\u003c\/li\u003e\n  \u003cli\u003eHigh-transparency quartz sleeve improves penetration\u003c\/li\u003e\n  \u003cli\u003eBest results when placed where water flows directly past the lamp\u003c\/li\u003e\n  \u003cli\u003eRecommended run time: short daily sessions (1–3 hours) rather than continuous use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhere and how should I install the coospider-repta UV unit?\u003c\/h3\u003e\n\u003cp\u003eInstall the lamp in a filter chamber, pond filter box, or a location with consistent flow to ensure water passes the UV exposure zone.

This coospider-repta 100W UV-C lamp targets pond keepers, commercial water-feature operators, large aquarium hobbyists and cold-plunge or spa owners who need a non-chemical way to improve water clarity and reduce odors across large volumes (roughly 1,000–10,000 gallons). It suits users who can install the unit where water flows directly by the lamp, follow basic safety precautions to prevent direct UV exposure, and perform occasional maintenance like quartz cleaning and seal inspections.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I use this UV lamp directly in a fish tank?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Place it inside a filter or behind opaque material; avoid direct UV exposure to fish and people.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How long should I run the lamp each day?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Run for short daily periods—typically 1–3 hours—until desired clarity is achieved.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"coospider-repta","offers":[{"title":"Default Title","offer_id":56801439809876,"sku":"B0FM3PY8HW","price":244.74,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/2652\/4244\/files\/coospider-repta-front-view.jpg?v=1786741793","url":"https:\/\/gardenluxe.co.uk\/products\/coospider-repta-100w-uv-c-aquarium-pond-sterilizer-for-1-000-10-000-gal-submersible-17-ft-cord","provider":"Gardenluxe Uk","version":"1.0","type":"link"}
