Pond Boss Forums POND CONSTRUCTION Creating habitat New 1/4 acre pond

I am not seeing the picture of the cinder block structure. Unsure of what this means: "something between the writes air lines". What is writes air line?
Depending on the brand and type of compressor I do not like 3/8" ID airline - generally this is too small causing too much back pressure on the compressor. But for a 1/4 ac pond the setup could be okay.

Also I do not like the cinder block diffuser arrangement - it causes more problems later. . Go to your PM area and give me your email address for other much better home made ways to create a base for the diffuser/s.
