What happened was indeed a form of hpoxia called "spring overturn". Its quite common in the wild, but in this case you actually did two things to "force" it to happen unknowingly. One, when you fertilized your pond the change in water color was the direct result of an algal bloom. When these algae died and sunk to the bottom of the pond they created an anaerobic environment as they decomposed. When you started the pumps and circulated the water from the bottom back up to the surface layers of water with little to no oxygen mixed with layers of normal water creating a hypoxic environment for the fish, killing them. In nature, this happens naturally in deep ponds or oxbows and is called "spring overturn" because spring rains create the current needed to circulate the low oxygen water deep up to surface

well said and exactly correct
I do not understand why everyone thinks all ponds need fertilization these days, for most it is unneccesary.

That's not high enough. Can you put a reducer on it and spray it up?
