I should also mention this is a canal in our lake, not a small pond, although it is limited to the upper two thirds of the canal and about 3-4 acres with an average depth of about 2 feet. The canal is about 50-60 feet wide and 5-6 feet deep in the center, shallowing up to the sides.
Would it be better to treat it with liquid Cutrine or granular?
Thanks!
