Calcium, too low

[markcolechin]

My calcium level at the moment is at 350
iam adding Tropical Marine Bio-Calcium in every day put the level will not go above 380. Is there any substance i can put in my Cannister filter to raise the level to a steady 400 or so then continue with weekly calcium top ups?
Cheers!!!!
