Soak and wash it in muriatic acid (HCl) to clear the pores, then rinse thoroughly before returning it to service.

Sintered Ball Airstone

Divide your total air flow by the 2 LPM each stone passes — a 60 LPM blower, for example, will run about 30 stones.

It has a 4 mm barb, so standard 4 mm airline pushes straight on.

No — the body is self-weighted and sits on the base with standard tubing attached.

Yes, it is suitable for both fresh water and salt water.

Fine to medium bubbles, which give good gas transfer for the air volume used.

A small self-weighted airstone for fine to medium bubble aeration in aquariums, tanks and holding systems.
