I see. I am getting the gypsum really cheap so I would like to try that route first. Not sure I want to play the Alum/Lime game, even though it is proven to be more effective. Thanks for all your help, it's going to be a work in progress for awhile, that's for sure.

If I do put in all 2500 lbs and it doesn't clear to an acceptable level, can I put in another 2500 lbs? Or will I have to start all over and add 5000 lbs to equal the two 2500 lb treatings?
