rocket Posted September 11, 2009 Report Posted September 11, 2009 Are they equally accurate? Are they the same or is one easier to read/less complicated etc? TF100 seems to test for one additional thing. Is it significant? Quote
chem geek Posted September 11, 2009 Report Posted September 11, 2009 A comparison of the two test kits is here. I have both since I started out with the Taylor K-2006 and then bought the TF100. Personally, I like the pH test in the K-2006 better, but the CYA test is better in the TF100. One can always order individual components to mix and match though for the pH test the indicator dye is different in the two tests -- both are phenol red, but at different concentration due to the different sample sizes and comparator standards.

From reading somewhere I think it said that you need to buy new drops (reagents) every year. If that's the case should I wait until next year to buy a kit since will be closing the pool in a couple weeks. Don't want to have to buy again next Spring Quote
chem geek Posted September 12, 2009 Report Posted September 12, 2009 The manufacturers of the kits say you should refresh the reagents every year, but in practice not all the reagents are that sensitive and most will last 2 years and some even more. The most sensitive are the FAS-DPD reagents -- the powder (if dark and crusty) and the titrating drops (light sensitive), but since you use those the most they will probably not be enough for much more than a year anyway. The other tests you can keep for at least two years. The indicator dyes would be the more sensitive while things like the calcium buffer, acid/base demand tests, TA titrating drops, all will last a very long time (generally speaking, acids, bases and buffers last a long time). This link from Taylor can give you an idea of when a reagent has gone bad. Quote
