Alk & Calcium question

[blkspade]

Hey,

 

So since I've started i always try to keep my dkh about 10. So every week i add 2 1/2 caps too my 14 biocube. I always seem to test for the calcium and its 450-475ish. Should i be adding calcium when i add the alk buffer? Even if its always high? I don't think I've ever had to add calcium..

 

Can this be right?

Test calc an hour after you add the alk buffer and make sure you aren't getting a flux. If not no worries.
