I've had Instant Ocean come in at 1170, and as high as 1400

Get your water checked by the LFS, or use another kit

And just a simple reminder for us all ...
If something is out of whack, don't start adjusting things, question the test methods

Too often I've caught myself thinking about adjusting stuff .... bad reefer, baaaad

I agree Greg +1 I would question the testing method and try a different test kit, before starting to add MG.
