The UltraZap airstone is a 50 mm air stone that connects to an air pump line and breaks the airflow into a wide, gentle stream of fine bubbles.

It suits aquariums, fish tanks and ponds where you want steady, even aeration — the larger diameter spreads bubbles over a wider area than a small stone. Just attach airline tubing from any standard air pump and rest it on the bottom.

Good to know:
– Size: 50 mm diameter
– Connects to standard airline tubing and air pumps
– Produces a fine, even bubble stream for gentle aeration
– For use in aquariums, fish tanks and ponds
– Raises oxygen levels and keeps water moving
