We just recently built a 2 acre pond and it has finally almost completely filled just 2 feet shy from full pool. However, we are located in east Texas and full of red dirt and clay. This has created extremely muddy and stained water. What's the best/easiest/most efficient way to settle the clay particles floating and clear up the pond.

I read a lot on gypsum and googled a few products...

Is something like this what I'm looking for or am I way off
