Save yourself a bunch of time and hassle with trying to set up your own system and just go with a Vertex. Their systems are set up in packages ready to plug in and go. I always have people trying to purchase products to make their own system and the time they spend versus the money they save is very minimal. Vertex's pond lyfe systems will work perfect for a pond this size and depth and operate for around $6 per month, depending on what you are paying per kilowatt hour for your electricity.
Also, if you do decide to build your own system, stay away from the rotary vane compressors... they are very very loud, regardless of what some say. The Vertex Pond-Lyfe systems operate at about 48 db's at a distance of 15ft... they are quiet.
Also, rotary vane compressors need to be rebuilt every 8-12 months for optimal air flow.. compared to ever 18-24 months on the piston compressors that Vertex uses.
Warranty: another nice feature of the Vertex systems is the 2 year warranty they give you on their compressors, vs the 1 year of other compressors...
I have been doing this for almost 20 years... take my advise when I say spending a little extra upfront will save you more in the long run...
