personally I don't want to use anything that has a Ca level over 400. it is easy to bump it up if need be but hard to remove. I wouldn't touch anything that has a Ca level of 490.. thats for sure.. way way to high..
I like IO as it just really needs a Mg bump up, once you correct the Mg the Ca settles out at around 380 to 400 which is perfect..
