At the end of my first SLAM day 2, I ran out of the drops needed to read high FC levels. My goal is 31 FC, and I think I was there last night -- the diluted sample water was pink and reading 25 FC when the bottle of Taylor R-0871 emptied. None of the local pool shops carry a replacement, and online ordering will take at least 2 days. I also have a basic test kit. Please suggest what I might do to remain at shock level and not lose all the time, money, and effort I've invested.
