Aquascape® Weighted Aeration Tubing works great for aeration systems in ponds and water features. While many types of aeration tubing float to the surface, this tubing will stay out of sight, safely hidden at the bottom of the pond -- without the need for weights. Constructed of thick-walled, puncture-resistant, extruded PVC, this tubing will not kink yet stays flexible, even in cold weather.
