If the pelletized gypsum is the same as pelletizrd lime, then here is what I was told about pell lime vs. ag lime.

Pell lime is made of finer particles than the ag lime, and once the pellet is dissolved it will act quicker in the soil to change the pH. The reason that farmers don't use it more often is that it costs more than ag lime. The pellet lime once broken down has a greater surface area due to the smaller individual particles, that's why it acts quicker.

Now, how this applies to a pond is beyond me!
