Calcium Tests

Thanks. API has always been pretty accurate as far as I can tell but I bought their reef master test kit and the calcium is about gone so I figured I would ask about other options.

I have used both salifert and Api. I used Salifert for a long time until I was confident my Ca was diled then went to a far cheaper kit---API they last 4 years too.
