Alk kits are reproducible if you use syringes (supplied) and shake the reagents prior to using. Then calibrate with norms 3.9 meq/L standard and you are goldentuberider said:I've found the Alk kits in the SeaChem kit to be garbage, neither of them tested anywhere within the range of any other kit. It's like they are from a different planet.

I'm fine with API reagents using a syring and calibration to standard.
For alk, almost everyone uses the same indicator/reagent.
