The answer is yes and no. Let me explain my goofy answer. The pond in question is a pond 100 x 300 and five feet deep. Currently has one diffuser in the middle of the pond and a 4.6 cfm compressor. And the specific question was about adding a larger compressor producing 11 cfm. The 100 x 300 pond should have at least two diffusers but more like three diffusers due to the depth. (CFM = Cubic Feet Per Minute)
Going from 4.6cfm to 11cfm would provide plenty of air and the boils you see now would be much larger and a little higher, plus it would move a lot more water, if that amount of air did not tear the diffusers first.
The down side of too much is

Our pond we add well water we were told there is no air in the well water find is 4540 by 6 foot deep how much air should we add to this
HI Dave, you heard correct on well water and springs do not have oxygen. Your pond is six feet deep and the size is 45′ x 50′? Feel free to use the contact page to reply and if you can send a picture along. At minimum we would most likely use a shallow pond (linear diaphragm) compressor and possibly one or two diffuser’s. The goal to achieve is 5=6 pp for game fish. Doesn’t seem like much but even dropping to 3-4 ppm the fish become stressed. Location like northern or southern states also make somewhat of a difference too, along with the nutrient loading and how much decomposing debris is in the pond. Please shoot us an email using the contact form along with the pond address and picture of the pond if you can.

Hello,my name is Tom we have approximately 60ftx30ft pond 7ft deep was wondering with one would you recommend thank you.
HI Tom, Good question and you are at a depth that bring questionable decision on what type of compressor. Linear air compressors are good to 6′ of depth. Piston type compressors can go up to 30. Yes there is a price difference as well.
With the linear type compressor going deeper than 6′ will require more frequent rebuild of the compressor diaphragms. So if you wanted to go with the linear type compressor I would recommend the PA8SWN with two diffusers. Place each diffuser a 1/3 of the way in from both ends of the 60′ length. Hopefully at those points the water will be shallower?
If you would rather go with a piston type compressor and not worry about depth then the PS10 would be the way to go.
Thank you for asking and hope this helps.
Darrell
