It is probably the Chitosan packet. WE was having a problem with them last year, but to my knowledge, the problem was fixed. I would contact the retailer for a replacement pack, but I would check the date of your kit first. This problem has been fixed for quite some time. As a result, my first inkling is that your kit is old. If the date is current, then just ask for the replacement pack. LD Carlson keeps me supplied for emergencies like this, but I haven't had to send one in over 6 months. If you have any problem with your retailer, let me know and I will send you what you need.
