Clean, healthy water starts with reliable aeration. The Single 9 inch Rubber Membrane Diffuser with Self-Sinking Base is designed to deliver maximum oxygen transfer while eliminating the headaches common with traditional diffusers. Unlike stone diffusers that clog and require frequent cleaning, this unit features a self-cleaning EPDM rubber membrane that sheds buildup automatically-keeping air flowing and maintenance minimal. The integrated self-sinking base ensures quick, hassle-free installation without the need for gravel or extra weights. Simply connect, drop it in, and let it perform. Engineered for ponds and lakes of all sizes, this diffuser increases dissolved oxygen, reduces muck, and helps maintain balanced water quality for healthier fish and clearer water. Built from heavy-duty materials, it's designed to last season after season, making it a smart investment for property owners who demand performance without compromise. With OWS, you get more than a diffuser-you get confidence that your water is being cared for by equipment built to perform.
