Need a Little Help With New Salifert Ca Test Kit

Also, did you roll it around and mix the salt prior to using it? I know sometimes with IO and RC they settle out
 
Maybe I was doing something wrong last night??? I added 3 oz BRS Ca last night. This morning Ca is testing at 640😳
 
Any other CA test kits sitting around? You've probably already tried that.
No, I don’t have another kit handy and my LFS is a Petco so, of course, they don’t carry them. Nearest LFS with any decent saltwater items is 45 minutes away.
 
Okay, I HAD to have been doing something wrong last night. Just tested the newly mixed batch of water and it’s at 440 ppm Ca. Now, the question is, what was I doing wrong last night.
 
Crazy results appear if you try testing a drop @ a time.
Put in 60 ml of titration all in 1 shot, it should be pink, then drop by drop until it turns blue.
 
Hunh, totally different than the Salifert calcium test I have. That explains a lot. I guess if I had paid attention to what was said in the first post...
