The Aqua Source stainless steel air dome diffuser is an ideal option to place anywhere in the pond should you need extra aeration, for pump fed systems with no bottom drain diffusers, or especially for separate bio chambers. Made from 316 grade stainless steel, it is perfectly fish safe. Weight of 3kg prevents the dome from moving around in the pond. Comes as a complete unit, all you need is some 12.5mm airline and an airpump.
