Product Description

If your aquarium, garden pond, or DWC hydroponic setup has been looking a little sluggish, chances are your fish (or your roots) are gasping for more oxygen. The Pawfly 6" Bread Air Stone is built for exactly that job — and it takes it seriously.

At 6" diameter x 2" tall, this chunky round diffuser is sized for large environments where a tiny air stone just won't cut it. It pumps out a rich wall of medium-sized bubbles that dissolve oxygen efficiently into the water column, keeping aquatic life healthier and more active.

Weighing in at 30 oz, the flat-base design means it drops straight to the bottom and stays there — no floating around or tipping over while bubbling away. You'll need a decent air pump (over 20W recommended) and either 3/16" or 3/8" ID airline tubing to get it running. It outputs up to 30 L/min of air, so pair it with something with real power.

Before first use, soak it completely in water for at least 3 hours. And give it a brush clean every few weeks to prevent clogging — it's a small chore that keeps performance dialed in.

Note: This air stone is designed for large aquariums, ponds, DWC systems, and aquaculture setups. It is NOT suitable for small fish tanks.

Interesting Points

Dense Bubble Output That Actually Works

The bread-style design produces an abundant cascade of medium bubbles across a wide surface area, maximizing oxygen diffusion for large water volumes.

Stays Put — No Drifting

At 30 oz with a flat base, this air stone sinks fast and sits stable on the bottom even when pumping at full blast — no anchoring required.

Built for Big Setups

Whether it's a large aquarium, an outdoor garden pond, or a DWC hydroponics reservoir, this stone is sized and rated for environments that need serious aeration.

Easy Maintenance

A quick soak before first use and regular brush cleaning is all it takes to keep this bubbler performing like new for months.
