Hi Brian I did the same thing except I used a 4 inch piece of pvc and filled it with the pellets and then shot water from the well through it and out a nozzle from the shore. I also had placed a mason jar of pond water and a mason jar of pond water and a little of the gypsum mixed in it. They have both sat for 2 weeks now and the clarity is still better in the strait pond water over the mixed! Will keep you posted on the results of my test. I couldn't find anything other than the pellets here in North Alabama. Oh well as you say live and learn.
