Fishman - Many, many thanks for your post! I just looked at my test kit last night and also realized that I have been reading the results upside down. I have done this six times and did not catch my mistake. I thought I had a hardness reading of 12, but when I turn it rightside up, I get a hardness of 70. You just saved me the cost and backache of adding 5 tons of lime! I also owe you a steak dinner if you are ever traveling through Pacific Missouri!
