My setup is also very similar. I purchased my tubing and the Vertex disks from http://shop.hoosierpondpros.com/Aeration_c3.htm
He is a sponsor and active member here. These are only the diffusers so like many I built my own bases and sunk them in my pond.
I ended up running air from my house but was only about 80 feet to the water line then the weighted hoses from there.
Like RC I did the same with the heater hoses. There is tons of information on here for DIY setups.

The vertex disks have a built in check valve as well.
