An air stone is used with an air pump and airline to create a flow of bubbles in your pond. This allows oxygen in to the water which is vital for healthy water, plants and fish.
We carry a varied collection of air stones here at Swell UK. All our own excellent brand, made to the highest standard and providing the very best performance, every time. Made from a refined ceramic material, each stone is long lasting and provides an even distribution of bubbles.
Whether you need a small stone for a tiny pond or aquarium or a larger one for big ponds, we are sure to have everything you need.
