Innovative New Air Delivery Hose for Ponds
Our high-quality Sinking Airline is an essential addition to any pond system. Designed to rest naturally at the bottom of your pond, this airline tubing ensures optimal placement of air stones and diffusers for better water circulation, oxygenation, and overall aquatic health.

Promotes Optimal Water Circulation
By positioning your air stones and diffusers at the bottom of the water feature, this sinking airline helps promote a more even distribution of oxygen, which enhances the circulation of water throughout the entire pond or tank. This is particularly beneficial in preventing stagnant areas, promoting better filtration, and keeping your fish and aquatic plants healthy.
