Hagen Calcium Test

[Aquattro]

Jon, you're right. Maybe I need to read slower. However, I also used the Ca kit and didn't get results matching my Salifert kit. This thread came up about a year ago and many people responded much the same as this thread. Some found problems, some didn't. This says to me that the Hagen kits are at best inconsistent. I've never heard anyone say that about Salifert, so for the extra coupe of dollars, I'll choose Salifert. JMO.
