Premium Small Round Air Bubble Stone for Aquariums & Hydroponics

High-grade porous ceramic material ensures ultra-fine oxygen dispersion for maximum aeration efficiency. Precision-drilled micro-holes create uniform bubbles to enhance water circulation and oxygen levels. Corrosion-resistant design withstands continuous underwater use in freshwater/saltwater environments.

Compact circular shape (2.5cm diameter) fits all standard air tubing for versatile placement in nano tanks, ponds, or hydroponic systems. Specially fired ceramic surface resists clogging from algae or mineral deposits.

Ideal for tropical fish breeding, shrimp habitats, aquaculture operations, and DWC hydroponic setups. Compatible with 3/16" airline connectors—no tools required. Sold in bulk quantities at wholesale-exclusive pricing.

Note: Includes stone only (air pump sold separately). NSF-certified materials guarantee aquatic safety.
