Pond Boss Forums GENERAL QUESTIONS Muddy water pellet gypsum

Here's some good guidance on calculating how much gypsum or alum is needed. I found I needed about twice the calculated amount but it was raining a lot during the time I was applying gypsum and I lost some downstream I believe. I ended up using 4500 # in a 1.8 acre pond (estimated 8 acre-feet).
