Alumina Air Stones
EasyPro Alumina Air Stones provide excellent aeration for Koi ponds and water gardens at a fraction of the cost of other diffusers on the market today! These quality units are available in several sizes to fit your specific needs.
- “Alumina” airstones – three times stronger than white silica airstones! Produces a finer bubble with no increase in 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
- More resistant to ozone
- Creates finer bubbles for increased aeration efficiency with no increase in pressure
