Thank you Bruce and deerwoman
After I spoke to you on the phone Bruce I came home and my wife suggested that I use a lice comb. I ran to the local drug store and with a little work I was able to remove all the clumps. I mixed another batch of EZ-100 without the NB-KU and it mixed up nicely. Suggestion to everyone don't mix NB-KU (or anything else for that matter) with EZ-100. I love happy endings, Alan
