Hello,
Received my kit today. According to the strips I was between 30 and 50 but couldn't differentiate the colors enough.
I ended doing the test 3 times. First time: Followed the directions and on the fourth step I couldn't get it to turn blue after 20 drops of R-0010. Then I noticed this note: *High chlorine levels may bleach out endpoint. If this happens, dechlorinate sample with 2 drops of Taylor reagent R-0007 prior to testing. I typically run my TC around 5-6.
2nd Test. Added the R-0007 at the beginning. All went well, jumped ahead 6 drops no change, then did a double drop and hit 8 drops at the end nice blue(hmmm, maybe 7 but ok 8). I'll do another test (#3) and be more careful. Borates 35.
3rd Test. Added the R-0007 at the beginning to cancel out the bleaching. All went well, came out with a total of 7 drops. Borates 31.5. The extra drop from the earlier test wasn't needed. OOPS. But close enough.
Overall All I'm impressed with the test. It's pretty easy overall. The price was right with Special shipping rate and there are enough supplies to run quite a few test.
Testing from earlier in the day: TC 5.5, PH 7.8, TA 70, CH 625, CYA 65, Salt 4100, Temp 85
Chem geek points out a good note that it should only take a drop or two of the R-0010 to get it to turn. I think that chlorine levels above 5 may need to add the R-0007 to dechlorinate the sample.
Also having a speed stir make this test much more simple and quicker. I don't have the speed stick, so it add, cap, shake, look, add, cap, shake look.
Good test overall.
