Ryan, my half-acre pond is of similar specs as yours except for size. I did all configurations myself four times before finding the right system. Two Thomas 8011 Series Thomas Compressors (220v) Diaphragm compressors failed within the first year due to not installing cooling fans in the pump housing. Moved to a Gast Rotary Vane Compressor, RV33, 1/4 hp unit with two cooling fans configured to pull/push air through the cabinet, two Matala Single Air Base w/9 inch disc diffusers. This system works and runs consistently within the temperature specifications of the manufacturer. Summer dry heat up to high 90's and low 100's. The biggest issue my opinion is the capacity and willingness of the supplier to provide you with the proper information with secondary consideration to their profitability. On this matrix (Scale 1-10) Fispondaerators rates 0. Keystone Hatcheries rates 10. It was an expensive lesson but one I most willingly share to help you avoid a similar fate. My fault completely - trying to save money initially: Bad or no advice, cost around $1000. Cleaning of invasive plants $1200. The new system, complete less than $1000. Hope this helps.
