Overview

  • KOOI spherical air stones diffuse air through a porous stone body to produce a distributed stream of bubbles. Two sizes are available: 22 mm diameter with a total height of 35 mm, and 28 mm diameter with a total height of 40 mm. Both connect to 4 mm airline tubing and are intended for use with small air pumps.
  • The stone bodies are sintered at 1,400°C. Applications include public aquariums, aquaculture facilities, fish tanks and ozone diffusion systems. Soak the air stone in water for 30 minutes before use, then connect it to the airline tubing and air pump. If clogging reduces bubble output, remove and clean the stone before reuse.
