Overview

  • The KOOI Blue Whale Series aquarium air stone disc is designed to create a broad curtain of fine, evenly distributed bubbles. Its carborundum diffuser is sintered at 1400°C and uses a 10 mm-thick air stone layer with a uniform pore structure for smooth air discharge and reliable everyday aeration.
  • The integrated, seam-free housing combines a low-profile round body, rounded edges, and a built-in air connector. Available diameters include 5 cm, 10 cm, and 13 cm. The 5 cm version uses a 4 mm connector, while the larger versions use an 4 mm amd 8 mm connector.
  • For consistent performance, clean the air disc every 1–2 months according to aquarium conditions. Soak it in a suitable cleaning solution, gently brush away deposits, and rinse thoroughly with clean water before returning it to service.
