WaterTreats Glass Bonded Silica Fine Pore Airstone 1.5” x 1.5” x 12” w ½” MPT, Stainless Steel 1.5 CFM
- Introduces oxygen into water – fine bubbles mean more air!
- Perfect for applications in tanks and small ponds
- Stainless Steel Fitting
- Top quality and best performance airstones – made in the US from a solid piece of glass bonded silica
- Low maintenance – fine pores mean that they don’t get clogged with small dirt particles, if they need cleaning, just give them a wash in a acid bath (recommended yearly)
- Long-lasting – material quality means that the stones won’t degrade over time like alternative stones do (if properly cared for)
- Air stones have a low air resistance – meaning they are great at pushing air through their pores
