Guy's,
Thanks for the great post. Problem solved. I found some #50 lb bags of gypsum from a USG supplier. Ended up going to a drywall supply distributor in our area, and he ordered it in. It ended up costing $80 for 1000 lbs. This would be alittle pricey if I had to do this often. I used the calculator listed in one of the earlier threads and applied the gypsum from the bank using a trash pump 3in in 1.5 in out with a 55 gal drum. This created an excellant mixing method, and was not to much work. The next day I went from 1 inch clarity to 3 in. That was @ 2-3 wks ago by the time I got the whole process put together. I am going out right not to retest the water. Clarity is around 18 in now. The water looks great.
