During the Chlorine Test, it says to use the "Chlorine Only" tube. Any particular reason that this is labelled so specific? I bought the magnetic stirrer kit and have been using the "Chlorine Only" tube with the magnetic stirrer. Is this OK?
It's fine to use the magnetic stirrer in it. The "chlorine only" cylinder is there for a very benign reason. Over time, the FAS/DPD test will start to leave a dark residual on the sides of the cylinder. By using only one, you keep the other one clean for all the other tests.
It takes quite a while for the cylinder to darken. It doesn't affect the validity of the test but if it bugs you, it is readily cleaned with a 1:1 dilution of muriatic acid.
If you're careful with the arrangement, you can get the speedstir, the cylinder that came with it, and extra stirbars all in the same case. That leaves one cylinder for FC, one for TA, one for CH, and the mixing bottle for CYA fits on the speedstir, too.
