Massive difference between salifert and red sea calcium tests!

[FishNerdVlogsYT]

So today i switched from red sea tests to salifert and WHAM the calcium skyrocketed from 350 (with red sea test) to 450 (with salifert)... I get that different brands can have different results but come on... 100 ppm? Thats a bit crazy. Glad I didnt try tp bring Ca up just because of the red sea test because it would be at 550 rn! [emoji23][emoji28] anybody have similar experiences?

I use Salifert and don’t have Red Sea to compare to but when I sent in ICP and a Triton sample both results were within 10 of Salifert test [emoji16]
