Sounds right on IME
. I use IO and it always test between 340-360 ppm Ca
. I add some Kent Turbo Calcium to get it to ~425 before use.
I am hoping it is just a bad bucket
I have been seeing the same complaint you have on many different forums for several months now atleast
. I'm not sure a bad batch could remain "around" for that long but who knows...
