Buying my first TF-100 today for a new pool currently under construction. I am looking at adding the XL option. I'm kind of a nerd and see a lot of unnecessary extra testing while I am getting my bearings. I can't tell by looking at the site which of the reagents are increased with the XL option. Is that posted somewhere and I am just missing it? If not, can someone here tell me which reagents come with the XL?
As for the SpeedStir. I brew my own beer and use a magnetic stir plate to grow brewer's yeast. Is there something special about the SpeedStir? Or would I be able to drop a 1" stir bar (I have several) in my test tube with the reagent and use that?
Also, for the extra stir bars if I go with the speed stir, will any standard 1" stir bar work? Like I said, I have several for use with my other hobby.
