No fish to worry about. It is a pond for swimming, and I will pay attention to ph afterwards.

Then I'd still put the 150 pounds in the tank, pump in the water. Stir, until it becomes a saturated solution and pump off the top, not sucking up any sediment. Keep repeating until the sediment is all dissolved.

Spray the dissolved alum over as much of the pond surface as possible every time you pump out of the tank.
