last I heard was that Salifert was going to include a reference sample with the kits, I honestly don't know if they have actually resolved the problem.
As far as using Salifert again, probably not going to happen as I'm totally happy with the LaMott kits, the readings are exact, you can do the test 4-5 times on the same water batch and the readings are incredibly consistent....Now I'm a dedicated LaMotte fan....Worth the few dollars more IMO.....Here's the best part about the LaMotte kits, you can call the tech support # and talk to an actual human if you have ANY questions about the kits.......... I had some questions about the dKH kit and conversion to aquarium readings, the guy answered my questions and gave me even more advice than I asked for.....Salifert Doesn't offer this free service
, LaMotte does

Ever wonder why Salifert has no email contact information, no US phone #, heck they don't even publish the salifert.com website on their products. Even the Salifert website doesn't have a "contact us" link,...... It's almost like they don't want you calling or emailing them, buy our product but leave us alone kind thing
