Prev owner left me a Taylor K-2005 test kit with a fair amount of juices left, but unknown age. This is like the good kit (K-2006) without a FAS-DPD setup. Question is, should I just buy a FAS-DPD test or should I buy a whole new kit? Do reagents go bad in a couple years time? If just FAS-DPD, is a Taylor K-1515 the appropriate kit? Anywhere to buy one locally near Gurnee, IL or in Milwaukee?
Also, if or should I say when I start doing borax, guess I'll need borax test strips - ditto on the where to buy.
Mange tusen takk for any help.
