I noticed the Alkalinity teat kit has an extra step to test alkalinity - 2 drops of R-0007. Why and what is it ? The HTH kit i purchased a couple months back , before I knew about and now have my TF100 only has 2 steps . 5 drops of indicator and drop by drop of the titrant.
Because I new using the TF100 and some results could be based on me doing something wrong I do use both to compare as a guide to see if I am OK in my testing. All test are coming out the same except this one - When I use the HTH , 2 step I get a result of 100. When I use the TF100 with the 3 steps I get 140 - Got to be me or the R-0007 , 2 drops I add does something that creates the variance -
