I have a six year old pond with a surface area of about one half acre, and a maximum depth of fifteen feet. The pond is fed mainly by a spring, and is stocked with bluegills, walleyes and largemouth bass.
The pond water is currently cloudy, and using a freshwater test kit for my aquarium, the pH is 6.0
Which option is better for solving this problem, using aglime or gypsum.
Thanks in advance.
