If you have a pump producing too much pressure/volume for the diffusers you wish to operate at that time, you can always install a waste bleeder in the system.
At any place where you have an existing manifold, or can easily install a tee, run a short piece of hose into the air with a valve on the end. Leave that valve cracked, so that a small amount of compressed air is always wasted to the atmosphere - as opposed to operating the system above the design parameters of your diffusers.
If possible, I would place the waste bleeder at some place I travelled past frequently on my daily or weekly routines. If you hear the bleeder just screaming air, then you know you have a freeze up in your line to the diffusers. If it is not making any noise at all, then that signals several other possible problems that are nice to diagnose early.
Cody Note - Good advice as an option above. I have seen this done for several aerator systems. When you have this situation where you are releasing excess air volume, why not add another diffuser and put that wasted air to work moving water in the pond.?
