``````````Aquadyne Rhino Retro 3" w/ Air Bladder
The Aquadyne Retrofit Bottom Drain is a stable and rugged over the liner bottom drain for those who do not want to install a drain through a liner, or for pre-constructed ponds that do not have a bottom drain. This drain is especially useful for pond and aquatic environments that have pre-existing liner, concrete, or any other situation that would not allow underground plumbing to be installed.
Rhino Retro Drains with Air Diffusers allow you to easily add much needed air circulation to ponds that increase oxygenation in hot weather and also create a sediment sweeping action due to the rising of thousands of air bubbles per second which adds circulation to the pond and helps keep the bottom of the pond cleaner.
