- In some situations it is easier to locate a compressor near an existing power supply that is far away from the pond and extend the tubing rather than run power down to the pond's edge.
- Typically a single, larger diameter, poly tubing will carry all the air from the compressor down to the edge of the pond where the valve assembly will be located. This prevents having to run multiple smaller lines between compressor and shore.
These assemblies are simply an "adder" to the kit cost. A single line set up coming off the compressor is included along with a modified valve assembly for installation by the pond.
