We have airline and tubing choices for delivering air to your pond. We have the standard airline that is typically used in short term situations during seasonal changes or for temporary holding tanks for fish. The weighted airline is used for more permanent situations because it will not float to the top of the water, it is quick and easy to install and will last you years and years. So if you are looking for an economical temporary fix search through Airline and if you are looking for a more permanent solution search Weighted Tubing
