Lee, from what I understand, the amount of fertilizer you apply is based on your water clarity.
Using a secchi disk or the elbow wrist method, measure your water clarity, you want 18-24 inches.
I can't find my pondboss book, so I can't give you the exact amount, but the clearer the water, the more fertilizer. My water was clarity was at least 12', I put 3 gallons per acre, probably could have put 4.
Anyway, once you fertilize, monitor the water clarity every day if possible. If after 10 days to 2 weeks you still don't have the 18-24' water clarity, fertilize again. You may not want to put as much in as the first time, depending on water clarity. Keep monitoring the water clarity , fertilize if necessary. I gotta go to work. I'll be back with more.
