Formulated with a low-dose copper complex containing approximately 11.8 percent copper sulfate pentahydrate and about 3 percent elemental copper, it delivers steady residual performance without foaming or staining when used as instructed. This one-gallon treatment is ideal for service routes or experienced pool owners seeking a quarterly application that maintains clean, algae-free water with minimal follow-up. By maintaining consistent copper levels over three months, the 90311SKR helps reduce labor, prevent recurring blooms, and support clearer water throughout seasonal cycles.\u003c\/p\u003e\n\u003ch3 data-start=\"1301\" data-end=\"1319\"\u003e\u003cstrong data-start=\"1305\" data-end=\"1319\"\u003eHighlights\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul data-start=\"1320\" data-end=\"2136\"\u003e\n\u003cli data-start=\"1320\" data-end=\"1479\"\u003e\n\u003cp data-start=\"1322\" data-end=\"1479\"\u003e\u003cstrong data-start=\"1322\" data-end=\"1353\"\u003eQuarterly Protection Cycle:\u003c\/strong\u003e A single application maintains algae control for up to ninety days, offering low-maintenance scheduling for balanced pools.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1480\" data-end=\"1642\"\u003e\n\u003cp data-start=\"1482\" data-end=\"1642\"\u003e\u003cstrong data-start=\"1482\" data-end=\"1525\"\u003eEffective Against Multiple Algae Types:\u003c\/strong\u003e Targets blue-green, yellow, mustard, black, and common green algae, giving technicians broad-spectrum reliability.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1643\" data-end=\"1802\"\u003e\n\u003cp data-start=\"1645\" data-end=\"1802\"\u003e\u003cstrong data-start=\"1645\" data-end=\"1678\"\u003eNon-Staining and Non-Foaming:\u003c\/strong\u003e Designed to keep surfaces clear of residue and prevent foaming issues when applied under proper water balance conditions.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1803\" data-end=\"1972\"\u003e\n\u003cp data-start=\"1805\" data-end=\"1972\"\u003e\u003cstrong data-start=\"1805\" data-end=\"1835\"\u003eStabilized Copper Complex:\u003c\/strong\u003e Uses roughly 11.8 percent copper sulfate pentahydrate and about 3 percent elemental copper to maintain long-term residual performance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1973\" data-end=\"2136\"\u003e\n\u003cp data-start=\"1975\" data-end=\"2136\"\u003e\u003cstrong data-start=\"1975\" data-end=\"2005\"\u003eSimplified Dosing Routine:\u003c\/strong\u003e Requires only sixteen ounces per ten thousand gallons every three months, reducing treatment frequency and easing service demands.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3 data-end=\"114\" data-start=\"89\"\u003e\u003cstrong data-end=\"114\" data-start=\"92\"\u003eDirections for Use\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp data-end=\"261\" data-start=\"242\"\u003e\u003cstrong data-end=\"261\" data-start=\"245\"\u003eDosage Rates\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-end=\"304\" data-start=\"263\"\u003e\u003cstrong data-end=\"304\" data-start=\"267\"\u003eEvery 3 Months (Algae Prevention)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-end=\"439\" data-start=\"305\"\u003eUse \u003cstrong data-end=\"321\" data-start=\"309\"\u003e16 fl oz\u003c\/strong\u003e of \u003cstrong data-end=\"364\" data-start=\"325\"\u003eSeaKlear Algae Prevention \u0026amp;
