I have lost faith in Salifert alkalinity test kits. They really seem to vary. The one I have now reads 2 dKH lower than the Elos and the Hanna Colorimeter, and the Salifert alk kit I had before that read 3 dKH lower. That's pretty frustrating.
Thanks for voting everyone! Lots of interesting information here...everyone is all over the charts!

I've used both salifert and elos. I never noticed noticed a big difference between the 2 and prefer to use salifert but it isn't always easy to get

Salifert's calcium, alkalinity, and magnesium are all very similar tests. Salifert's alkalinity is a bit tricky because the color changes slowly over several drops from blue, to blue purple, to purple, to purple pink, to pink. According to customer service you're supposed to read it when the color is purple pink. This can be difficult to tell, but in all reality the difference is like 0.25 dKH all the way from blue to pink so who cares to be that picky? I wish Elos was as picky as the Salifert kits though, as with Elos (and API) you go up by quite a jump. I guess you get used to it. I just know that I don't want the color to change when I put in 7 drops (7 dKH), but I do want it to change when I put in 8 drops (8 dKH) because I want alkalinity between 7 and 8. Takes a bit of getting used to not knowing exactly what you're at when you're used to kits like Salifert. Last edited by Myka; 05-02-2010 at 12:35 AM.
