5cm Ball Air Stone With Metal Connector - 5 Pack

The Castle Dawn Aquatics 5 cm Ball Air stone is built for long-lasting, high-efficiency oxygenation in aquariums, deep water culture (DWC) systems, and outdoor fish ponds. Designed with a durable mineral-based body and a metal connector, this airstone outperforms plastic connector alternatives by offering superior strength, leak resistance, and a longer service life.

With a jetting volume of 5 L/min, it produces a rich flow of medium-sized bubbles, increasing oxygen solubility and promoting healthier aquatic environments. It’s well-weighted to stay securely at the bottom of your tank, delivering consistent airflow without drifting.
