Pawfly 4-Inch Air Stone Disc Diffuser (ASD100) - 4 Pack for Aquariums, DWC, Ponds

Maximize water aeration with a reliable diffuser

The Pawfly 4-Inch Air Stone Disc Diffuser is a compact, mineral-based aeration tool designed to work across a range of setups. Its disc-shaped design sinks gracefully to the tank bottom and stays in place with three secure suction cups. When connected to your air pump, it creates a steady field of bubbles that travel across the substrate, helping to promote water movement and visible circulation throughout the tank.

Key specifications and benefits

• Dense bubble output that enhances water movement and can help with surface agitation.
• Model ASD100 with a jetting capacity of 12 L/min; compatible with tubing 3/16" or 3/8" inner diameter.
• Made from mineral material sintered at high temperatures for a stable, inert surface around aquatic life.
• Bottom-landing design with three suction cups to keep the diffuser secure in a variety of tanks.
• Simple usage: soak the stone completely in water for about an hour before first use and clean periodically to maintain airflow.

Versatile deployments and practical care

Whether you are running a standard freshwater aquarium, a hydroponic DWC bucket, or a small pond, this diffuser can contribute to a steady bubbling pattern that aids circulation and mixing. Having a 4-pack means you can equip multiple tanks or reserve spares for a larger system.

• Suitable for aquariums, DWC systems, and ponds, with stable bottom positioning for reliable operation.
• Pair with air pumps greater than 4 W for optimal performance per the device specifications.

Installation and maintenance tips

Install by placing the diffuser on the tank bottom and attaching the three suction cups to a clean glass surface. Ensure the stone is fully submerged before turning on the pump. For ongoing performance, rinse or brush the diffuser to remove buildup as needed. Soaking before first use helps the pores release air smoothly, and regular cleaning extends the life of the diffuser.

Notes on longevity

This diffuser is designed as a durable aeration accessory that complements routine tank care and filtration. The 4-pack offers flexibility for multi-tank setups or future replacements.
