Air stone for aquarium BAHCO EB-3746, white, 25×25×25 mm

BAHCO EB-3746 is a compact white air stone sized 25×25×25 mm, designed to deliver fine aeration in small aquariums, breeding tanks and decorative individual setups. The porous material breaks incoming air into a stream of small bubbles that improve oxygen transfer, support water circulation and assist mechanical filtration by keeping particles suspended for easier removal. The air stone connects to standard airline tubing and is compatible with common aquarium air pumps suitable for small volumes.

Advantages

The small cubic shape and uniform porosity ensure consistent bubble output and even distribution of airflow. Its compact dimensions make the air stone easy to position inside tight spaces, behind decorations or within breeding boxes without obstructing the tank layout. Using a dedicated air stone reduces direct pump flow, creates gentler water movement beneficial for fry and delicate species, and can extend the operational life of connected equipment by moderating backpressure.

Suitable for

• Small freshwater aquariums and desktop tanks
• Breeding setups and fry rearing containers
• Individual decorative elements or plant areas requiring subtle circulation
• Air-driven filtration units and sponge filters in compact installations

Key specifications

• Color: white
• Shape and size: cube, 25 × 25 × 25 mm
• Material: porous aeration stone (ceramic or similar porous media)
• Connection: compatible with standard 4–6 mm airline tubing
• Output: produces fine micro-bubbles to enhance oxygenation and circulation

How to use

Attach the air stone to airline tubing from a suitably sized air pump and submerge it at the desired location in the aquarium. Position the stone where improved circulation is needed—near substrate, behind décor, or inside breeding enclosures—while avoiding direct placement against delicate plants or fragile inhabitants. Regularly check tubing and pump performance to ensure steady bubble flow; if bubble output decreases, clean or replace the air stone following manufacturer care guidance.

Usage recommendations

For optimal performance, pair the air stone with an adjustable air pump and use inline check valves to prevent backflow. Periodically inspect for clogging and lightly clean the stone by soaking in dechlorinated water or using gentle brushing; avoid harsh chemicals. Replace the air stone when bubble size grows irregular or output significantly diminishes to maintain proper oxygenation and circulation.
