i just tested my pond with some strips from the swimming pool supplier and my ph is 8 or higher and the alkalinity is 60 or more ppm. is this good?

i fertilized with 13-13-13 about 3 weeks ago and added about 2 tons of lime. my pond is about 3/4 acre.

my bream were stocked tuesday and that night we had about 4" of rain. due to the water shed, my pond rose 19". yesterday i started seeing bg die. any idea what might be going on?

is the chemistry of my water bad?
