Keep your oxygen levels in your pond or aquarium healthy with Alumina Airstones. Alumina Airstones are three times stronger than white silica airstones. They produce a finer bubble with no increase in back pressure. Inlet fittings are set into the body of the diffuser, making them much less likely to break or twist loose. Higher density means self-weighting. Cleanable with muriatic acid or chlorine.
