Improve aeration while increasing pond aesthetic appeal! Hagen Elite Bubble Disk is an economical addition to your pond that creates an eye-catching visual display of bubbles that enrich oxygen content for better fish health. Disk-shaped airstone diffuser produces a cylindrical bubble column that rises to the surface to increase surface agitation for greater overall water circulation and aquarium gas exchange. A decorative touch ideal for any pond. Airstones, curtains, and diffusers require an air pump and airline tubing for use (sold separately).
