That casing is the useful part: the stone itself is brittle, and the plastic ring protects it from the knocks that crack an unprotected stone. An inlet nodule inside the ring takes airline from your air pump, and air escapes through the pores across the exposed face, throwing off a steady sheet of small bubbles.

The result is the familiar pattern of weak roots, slow growth and disappointing uptake, followed by slime and rot once anaerobic organisms take hold. An air stone keeps the solution turning over and dissolved oxygen high, so the root zone stays aerobic and beneficial microbes thrive.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize it:\u003c\/strong\u003e 3 inch for small reservoirs, 4 inch for medium, 5 inch for large\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnect:\u003c\/strong\u003e fit airline to the inlet nodule inside the ring and run it back to the air pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlace:\u003c\/strong\u003e sit the stone on the bottom of the reservoir with the exposed face upwards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRun time:\u003c\/strong\u003e continuously for consistent oxygen levels\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaintenance:\u003c\/strong\u003e rinse between crops and replace once the pores clog and output weakens\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 Round air stone\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes available:\u003c\/strong\u003e 3 inch, 4 inch, 5 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Porous stone, part cased in plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e Inlet nodule inside the ring for airline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuits:\u003c\/strong\u003e 3in small, 4in medium, 5in large reservoirs\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":"3 Inch Round","offer_id":53445791973642,"sku":null,"price":1.49,"currency_code":"GBP","in_stock":true},{"title":"4 Inch Round","offer_id":53445792006410,"sku":null,"price":2.49,"currency_code":"GBP","in_stock":true},{"title":"5 Inch Round","offer_id":53445792039178,"sku":null,"price":2.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/82892_-_4_Inch.jpg?v=1785325166","url":"https:\/\/hydrocropshop.co.uk\/products\/air-stone-round","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
