Tropic marine test kit

I finally got my magnesium and calcium test kit from tropic marine yesterday. I ordered it from BA's online for $53.00. It tests Calium first and is acurate to 4ppm, then you continue to add this and that for the Mg test which has the same accuracy.

It takes a while to learn to use it and its one of those tests that you go blind trying to decifer. But it seems to be more acurate than other test kits I've used.
I'd give it 3.5 to 4 stars out of five.

I like Salifert. It's accurate and easy to use. I've seen many stores sell a variety of test kits, but noticed they use salifert for their own tests, even though it is a brand they don't sell.

I wish I could find a salifert Mg test kit in Calgary, maybe next time.
