Guess it is Time to Drain Some Water...

Raise the discharge hose up high to introduce more "head" to the pump. this will reduce the volume of water being pumped. Head is the height that the water needs to be lifted vertically before turning horizontal.

And / or put a pvc ball valve in the discharge and throttle it down to match the fill volume.
Both great ideas thank you!
