Each diffuser measures 4 inches tall and 2 inches in diameter, engineered to sink and rest on the substrate for stable, even aeration from edge to edge.\u003c\/p\u003e\n\u003ch2\u003eWhy these stones stand out\u003c\/h2\u003e\n\u003cp\u003eCrafted from washable silicon carbide, the stones are inert and durable, built to withstand regular use in water environments. The porous surface promotes consistent bubble formation, helping to distribute oxygen more evenly through the water and around plant roots or aquatic life. They are compatible with common airline tubing (3\/16 inch), making them a versatile choice for many setups.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cstrongstable in water\u003e: Each stone sinks to the bottom and sits firmly for steady bubble output across the tank floor.\u003c\/strongstable\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003cstrongtubing compatibility\u003e: Fits standard 3\/16 inch airline tubing for broad pump compatibility.\u003c\/strongtubing\u003e\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePerformance guidance\u003c\/strong\u003e: If bubble density seems low, consider pairing with a higher-watt pump (10W or more) to maximize aeration.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDurable, inert material\u003c\/strong\u003e: Made from washable silicon carbide; designed to be safe for aquatic environments; soak before first use and clean regularly to prevent buildup.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVersatile applications\u003c\/strong\u003e: Suitable for hydroponic systems, koi ponds, aquariums, and other setups; supports even bubble distribution and nutrient delivery in reservoir systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSetup and care\u003c\/h2\u003e\n\u003cp\u003eGetting started is straightforward. Submerge the stones for a 2-hour soak before first use to help saturate the material. Connect to your pump via 3\/16 inch tubing, place the diffuser where it can rest on the bottom, and power up. If airflow is insufficient, upgrading to a higher-watt pump can help maximize bubble production. Regular maintenance keeps the stones performing well over time: rinse with clean water and, if needed, brush away any buildup to prevent clogging.\u003c\/p\u003e\n\u003ch3\u003eReal-world scenarios\u003c\/h3\u003e\n\u003cp\u003eIn a larger fish tank, these stones can create a visible plume of bubbles that helps circle water and mix surface layers. In a hydroponic system, the aeration can assist root zones by encouraging gentle agitation and circulation. For koi ponds, the diffusers contribute to consistent water movement, aiding overall aeration without taking up extra space. A 6-pack gives you the flexibility to equip multiple tanks or zones within a single setup.\u003c\/p\u003e\n\u003ch2\u003eWhat’s included\u003c\/h2\u003e\n\u003cp\u003eA six-pack of large air stones designed for easy integration with standard pumps and reservoirs.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What applications is the COOMATEC 4x2 inch air stone best suited for?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Ideal for large aquariums, hydroponic grow systems, koi ponds, and other water setups needing steady aeration.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How should I maintain COOMATEC air stones to keep them performing well?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Soak before first use and clean regularly with a brush to prevent buildup.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"COOMATEC","offers":[{"title":"Default Title","offer_id":57199747465593,"sku":"B0BM3RKWWS","price":31.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0997\/8934\/1049\/files\/coomatec-aquarium-aerator-stone-4in-diameter-2in-height.jpg?v=1777778178","url":"https:\/\/petlyvox.com\/products\/coomatec-6-pack-large-air-stones-4x2-inch-diffusers-for-aquarium-hydroponics-and-koi-ponds","provider":"petlyvox","version":"1.0","type":"link"}
