I have a question about the test chemicals. I just received my refill kit for TF-100. This year up until now I have been using the chemicals I got last spring. When testing Alkalinity with last years chemicals I am at 80. When testing with the new chemicals I am at 160. The droplets of the R-0009 out of the new bottle appear to be coming out a lot smaller and faster than the bottle from last year. So I think it is the tip. I change the tip from the old bottle put on the new bottle and same thing smaller faster droplets. So now I am thinking the test chemical in the new bottle is thinner consistency. Has anyone else had this issue? I tend to believe the 80 is the correct number.
