As a reservoir grows, or as solution temperature climbs through summer, a small pump stops keeping dissolved oxygen up: roots turn brown and slimy, nutrient uptake falls away and growth stalls. One high-flow pump running several air stones keeps the whole system oxygenated and the solution moving.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSize the model to the total air your stones need, plus some headroom.\u003c\/li\u003e\n\u003cli\u003eStand the pump on a dry, level surface above the water line, or fit a non-return valve in the line, so water cannot siphon back into it.\u003c\/li\u003e\n\u003cli\u003eRun 19mm hose from the outlet to an air manifold, then airline to each stone.\u003c\/li\u003e\n\u003cli\u003eRun it continuously and keep the pump somewhere clean and ventilated so it stays cool.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLK-60:\u003c\/strong\u003e 60 L\/min (3,600 L\/h), 40W, 0.03 MPa\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLK-80:\u003c\/strong\u003e 80 L\/min (4,800 L\/h), 50W, 0.035 MPa\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLK-100:\u003c\/strong\u003e 100 L\/min (6,000 L\/h), 65W, 0.035 MPa\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlets:\u003c\/strong\u003e 1 x 19mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 288 x 196 x 193mm (all models)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower supply:\u003c\/strong\u003e 230V, 50Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing:\u003c\/strong\u003e aluminium motor casing, outlet buffer chamber, oil-free\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"BOYU","offers":[{"title":"3,600 L\/h (LK-60)","offer_id":53803794792714,"sku":"HYD-BOYU-002-01","price":98.45,"currency_code":"GBP","in_stock":true},{"title":"4,800 L\/h (LK-80)","offer_id":53803794825482,"sku":"HYD-BOYU-002-02","price":108.99,"currency_code":"GBP","in_stock":true},{"title":"6,000 L\/h (LK-100)","offer_id":53803794858250,"sku":"HYD-BOYU-002-03","price":118.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/boyu-lk-high-flow-air-pump-1.jpg?v=1790229373","url":"https:\/\/hydrocropshop.co.uk\/products\/boyu-lk-high-flow-air-pump","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
