I talked with vertex who helped me design a system. I went to purchase it and found it was a little to expensive for me. I have the ability to build my own cabinet, source my own fittings, and hook up the entire system for much less.

I feel bad using them for information and not purchasing, but I cant spend that much more just to show im thankful for their information.

With that being said they suggested a dual rocking piston compressor and 3 dual 9" diffuser setups. one in the 20' area and the rest will be in 10'.

I previously had a 1023 1/2hp gast rotary vane pump 10psi max 10cfm I got for $300 and it was basically brand new. seemed like a good deal.

So a few questions.

1. Since the max PSI is 10 and I don't want to work it at 10 psi constantly to extend the life of the pump. should I raise the deepest diffuser setup 1-2' off the bottom to not push the system?

2. I was planning on running weighted 1/2" ID hose. Will this suffice or should I go up in size. I found 100' increments for $140.00 each or $1.40/ft. Does this seem like a good price? seems like the average is $2/ft

Thanks for the help!
