Mazda 6 2010 - what coolant to use?

On my way home i noticed that my coolant was below minimum. I noticed that the coolant was blue, so I drove to the nearest gas station and filled it up with regular blue (not long-life) coolant. After I got home i read that the recommended coolant for these cars are F-22. Usually these coolants doesnt have blue color, so I have no idea why my coolant was blue (bought it not long ago).

Is it ok that I filled it up with regular blue coolant, or should I empty the entire thing and fill it up with F-22 or some other recommended long-life coolant?

"recommended coolant for these cars are F-22" There's a difference between recommended and what you have to use.
As long as you don't mix the colors either coolant should be fine. And these "long-life" coolant is simply made to last 2 WHOLE more years than regular. I would'nt care that it wasn't the recommended coolant as long as the one you put in doesn't harm the engine, which I doubt.
