Pond Boss Forums GENERAL QUESTIONS Help Perch in my pond dying quickly

Todd:

How much planktonic algae was in the pond at the time of the application?

What PPM were you shooting for when you applied it? For algae treatments, you calculate the volume of water in the pond, then look at the label to see what the target PPM application rate is for that specific type of algae, then apply it. (a combination of Table 1 and Table 2)

I would be running the aeration system 24/7 if you don't have a way to test the DO levels.
