Factor in the footprint of each cylinder, 5.1 in long and 1.15 in across, in the tank, DWC system or small pond where it will sit. Both stones together weigh 175 g, and since some reviewers describe the plastic body as fragile, handle it with care when you move it.\u003c\/p\u003e\u003ch2\u003eCylinder shape and bubble output\u003c\/h2\u003e\u003cp\u003eThe stone is a plastic cylinder made for continual bubbling.

Customers find it heavy and expensive, and durability is a concern as customers report it can break if not handled carefully.\u003c\/p\u003e","brand":"Pawfly","offers":[{"title":"Default Title","offer_id":44477371220031,"sku":null,"price":29.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/2409\/1199\/files\/pawfly-air-stone-2-pack.jpg?v=1794713572","url":"https:\/\/dogjointly.com\/products\/pawfly-aquarium-air-stone-2-pack","provider":"DogJointly","version":"1.0","type":"link"}
