Vertex Bottomline Self-weighted Tubing 0.75" 300' Single Spool

The Vertex Bottomline 0.75" Self-weighted Tubing is engineered for reliable, long-term performance in underwater aeration systems. Designed to stay firmly on the bottom of ponds and lakes without external weights, this 300-foot spool of weighted tubing is an ideal solution for efficient air delivery in both residential and commercial applications.

Built with durable PVC and a high-density construction, this tubing is resistant to kinks and cracking. The black, non-reflective finish blends naturally with aquatic environments while helping to reduce algae growth on the tubing surface. Its self-sinking properties simplify installation—no bricks, anchors, or add-ons needed.

At 0.75-inch inner diameter, it provides ample airflow with minimal resistance, making it compatible with most standard aeration compressors and diffusers. Whether you're servicing a pond, lake, fish hatchery, or aquaculture system, this tubing delivers consistent performance even under harsh weather or underwater conditions.

Perfect for those seeking dependable aeration plumbing, this single 300-foot spool allows for long runs with fewer connections, cutting down on installation time and potential leak points.
