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.

Unlike traditional airline tubing that tends to float, our sinking airline stays securely at the base, out of sight, and out of the way, providing a more aesthetically pleasing and efficient setup.

Promotes Optimal Water Circulation

This is particularly beneficial in preventing stagnant areas, promoting better filtration, and keeping your fish and aquatic plants healthy.
