Salifert Test Kits

[Keana]

I just got a CA test and it's not working.... I've tested many samples of my reef water and mixed salt/water change and by Salifert's test my Ca is literally off the charts! It never changes from pink/red to blue. I've used Salifert for years without a problem. My last bit of Ca test from Salifert gave me a reading of 410 and that used the last of my CA-3 reagent so now I'm stuck with this new/dead test kit. After what I have read about these tests lately and after this dud test kit I am no longer going to use them. The quality seems to be going down hill, and rapidly.
