Lee's Discard-A-Stone Aquarium Airstones
Lee's Discard-A-Stones are disposable air diffusers that produce coarse, fine, or extra-fine (slim) streams of tiny bubbles for maximum air diffusion. These airstones have reusable airline inserts. They are excellent for airstone-drive applications or just for decoration. Available in 2 packs and 6 packs. Check out our selection of suitable aquarium air pumps too.
