Quick Overview
Unique EHEIM air stone is compatible with all brands of air pumps, using standard 4mm inner airline.
Size : 3.5 x 3.5 x 5cm (L x W x H).
Works with EHEIM air pumps or any other air pumps. Includes suction cup and connection for air hose 4/6 mm. The air flow level and apperance is adjustable.
The felt washer of the EHEIM outlet may become clogged after some time. This will lead to an increased counter pressure reducing the flow rate and increasing the wear to the diaphragm. You should therefore replace the felt wahser of your EHEIM outlet at regular intervals.
