NEO Normal Original Air Diffuser - Aquario

Description NEO Air Diffuser creates tiny air bubbles in comparison to other air stones.  This allows for a reduction in noise and splash while allowing an increase in dissolved oxygen in an aquarium.  It is made of transparent acrylic, which makes it durable and less susceptible to breakable during cleaning or maintenance. In order to produce smaller bubbles first, soak the diffuser in water for 30 minutes.  Once the bubble diffusion begins to slow down, then soak it in bleach and rinse it with completely water to ensure all the bleach is washed off.
