How big is your pond? And, what pump did you buy? Do you have a pump curve that you could share?
About 3/4 acre. Maybe slightly smaller. 12 ft deep at most, probably 8 ft average. I bought the blue diamond 120. What’s a pump curve?
QA is right, your pump is barely up to the job. Since it's brand new, you might consider returning it.
You want 2 diffusers minimum for your pond, for your pump to work, they will need to be in shallower water than you expect. This is the time to make that call.
