Can someone give me advice? I'm dosing every other day with Concentrated reef-building complex by Brightwell (http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=19751). I cant seem to raise the calcium levels above 360ppm. I have been dosing for a week and the the levels are not going up. My dhk is hovering at 10.
Any ideas?
