WaterTreats 4 Way Diffuser Manifold Kit w/ 4 x 1 1/2″ x 1 1/2″ x 3″ 1.4 cfm

• Introduces oxygen into water – fine bubbles mean more air!
• Perfect for applications in tanks and small ponds
• 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
• Long-lasting – material quality means that the stones won’t degrade over time like alternative stones do (if properly cared for)
• Self-weighted
• Air stones have a low air resistance – meaning they are great at pushing air through their pores
