Hi Mom,

Thanks for the info. I will try the dilution to see what happens. Also, could you or someone else please explain the difference between the "DPD" test kit which I have (from 2001 by the way), and a "FAS-DPD" test kit? I am really not sure what the difference is. I tired to look and Googled it, but it really was not much help.

Thanks.
