The Vevor pond aerator air diffuser and hose kit is designed to work with an aeration compressor to boost oxygen levels in ponds and lakes. It includes an 8" silicone aeration disk with a weighted 304 stainless steel base and a 100' self-sinking 3/8" ID EPDM rubber hose. The diffuser releases fine bubbles for efficient oxygen transfer while helping improve water quality and reduce sludge buildup. Its durable, tear-resistant materials are built for long-term underwater and outdoor use.
