Blanket weed (Cladophora or Spirogyra) is the bane of UK pond keepers, spreading rapidly in warm, nutrient-rich water and quickly smothering pumps, filters, aquatic plants and pond liners. Left untreated, it depletes oxygen, traps fish and chokes the natural balance of your pond ecosystem. Our concentrated liquid formula gets to work immediately on contact, targeting the blanket weed's cellular structure and breaking it down within days — without harming your fish, aquatic plants, frogs or other pond wildlife when used as directed. At 1 litre treating up to 10,000 litres of pond water, it offers exceptional value and consistent, professional results.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable border=\"1\" cellpadding=\"8\" cellspacing=\"0\" style=\"border-collapse:collapse;width:100%;max-width:600px;\"\u003e\n  \u003ctr\u003e\n\u003cth style=\"background:#1b2631;color:#fff;text-align:left;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"background:#1b2631;color:#fff;text-align:left;\"\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTreatment Type\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eConcentrated liquid algae\/blanket weed treatment\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCoverage Rate\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1 litre treats up to 10,000 litres of pond water\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTarget Algae\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBlanket weed, filamentous algae, green water algae\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAction Speed\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFast-acting — visible results within days\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSafe For\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eFish and wildlife when used as directed\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFormula\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eConcentrated liquid — easy to measure and apply\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAvailable Sizes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1L \/ 2.5L \/ 5L\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eApplication Method\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDilute and apply directly to pond water\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e⚡ \u003cstrong\u003eFast-acting formula\u003c\/strong\u003e — starts working on contact with algae;
