Pawfly 12-Inch Cylindrical Aquarium Air Stone — Large Tank Aeration Diffuser The Pawfly 12-Inch Cylindrical Air Stone is designed for sizeable water environments like expansive freshwater tanks, garden ponds, DWC setups, and active aquaculture systems

Its long, 1

9-inch diameter cylinder creates a broad column of bubbles that travels through the water, helping to introduce oxygen and promote steady circulation across large volumes

When deployed, you’ll notice a clean, continuous plume of micro-bubbles that diffuse through the water column

With a jetting capacity of about 30 L/min and a pump power above 20 W, it supports reliable diffusion for hours, contributing to consistent water movement without dramatic surges

Stable, reliable in-water performance Stable in water: Two square end holders keep the diffuser oriented and prevent drifting during bubbling

Weight and design: Approximately 34

8 oz, helping it stay put in larger water volumes for steady operation

Simple setup and ongoing care Ease of use: Soak the stone completely in water for 3 hours or more before first use to prime the micro-holes

Maintenance: Clean regularly with a soft brush to prevent buildup that can affect diffusion over time
