OK, I got my 0870 and 0871 and #3 reagents. I don't have a graduated cylinder yet so I tried using a measuring spoon into a clear glass and I don't think it's real accurate but it does lead me to a question. If I'm showing any CC at all does it mean I have an algae situation trying to start? What CC readings should I be worried about? I'm going to a pharmacy to see if I can find a container to work for the tests, if not I'll get one somewhere.
