The wide, flat disc sits neatly on the bottom of the tank on \u003cstrong\u003erubber feet\u003c\/strong\u003e, and the protective casing shields the porous stone from knocks. Across that full 200mm surface it releases fine, consistent bubbles that lift dissolved oxygen and keep the whole reservoir turning over rather than sitting still. It takes a \u003cstrong\u003enon-standard 8mm airline\u003c\/strong\u003e and needs a \u003cstrong\u003ehigh-output air pump\u003c\/strong\u003e to drive it, which is what makes it a large-tank component rather than a small propagation part.\u003c\/p\u003e\u003ch3\u003eKey Benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh oxygen output\u003c\/strong\u003e across a \u003cstrong\u003e200mm\u003c\/strong\u003e disc, raising dissolved oxygen in the whole tank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEven bubble distribution\u003c\/strong\u003e that covers a wide reservoir area rather than one narrow column\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduces stagnant zones\u003c\/strong\u003e and keeps nutrients properly mixed between top-ups\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupports healthier roots\u003c\/strong\u003e, which in turn improves nutrient uptake and growth rate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable build\u003c\/strong\u003e with a protected casing and rubber feet for stability on the tank floor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhy Does Dissolved Oxygen Matter in a Reservoir?\u003c\/h3\u003e\u003cp\u003eIn hydroponics, oxygen is as important as the feed itself. Roots in still, poorly oxygenated solution cannot take up nutrients properly, so you get slow growth and weak roots even when EC and pH look right, and low oxygen invites the anaerobic conditions behind most root problems. Constant aeration keeps dissolved oxygen high and the root zone aerobic.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition:\u003c\/strong\u003e lay the stone flat on the bottom of the reservoir, fully submerged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnect:\u003c\/strong\u003e attach to your air pump using \u003cstrong\u003e8mm airline tubing\u003c\/strong\u003e (non-standard size)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump:\u003c\/strong\u003e use a high-output air pump, as an undersized pump will not supply the whole disc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRun time:\u003c\/strong\u003e leave it running continuously, day and night\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintenance:\u003c\/strong\u003e rinse the stone between crops so the pores do not clog and output stays even\u003c\/li\u003e\n\u003c\/ul\u003e\u003cdiv class=\"hcs-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct type:\u003c\/strong\u003e Circular air stone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 8\" (200mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Flat disc\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAirline size:\u003c\/strong\u003e 8mm (non-standard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePump requirement:\u003c\/strong\u003e High-output air pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e Protective casing, rubber feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Hydroponic reservoirs and nutrient tanks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Air Stone","offers":[{"title":"Default Title","offer_id":53445791842570,"sku":null,"price":15.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/200mmFlatCircularAirStone.jpg?v=1785295002","url":"https:\/\/hydrocropshop.co.uk\/products\/flat-circular-air-stone-8-200mm","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
