QK Air Stones are premium-quality ceramic air stones designed to provide fine and consistent aeration in ornamental ponds, koi ponds, and aquaculture systems. Available in a variety of sizes and fittings, including 4mm and 3/8” connections, these air stones are compatible with most high-quality air pumps and ensure optimal oxygenation throughout the pond.
The ceramic construction of QK Air Stones produces uniform micro-bubbles, enhancing water circulation, supporting beneficial bacteria in filters, and promoting healthy fish growth. Each air stone comes with a protective plastic end housing, preventing damage from contact with pond surfaces and ensuring long-lasting performance.
Sizes available include 50mm ball (4mm fitting), 30mm x 130mm can (4mm fitting), 40mm x 170mm can (3/8” fitting), 50mm x 200mm can (3/8” fitting), 50mm x 300mm can (3/8” fitting), 130mm round (4mm fitting), and 200mm round (3/8” fitting). This variety allows pond owners to select the correct size and type for their specific filtration and aeration needs.
QK Air Stones are ideal for improving dissolved oxygen levels, maintaining water quality, and supporting koi and other ornamental fish health. They are durable, efficient, and easy to install, making them a must-have for hobbyists and professional pond keepers seeking reliable aeration solutions.
