hey NM, my calcium was just on the borderline low end of the target range for my test kit. i forgot the brand of this one, but said 20-25 drops is the range, and i was at about 19.5....
anyway i just recently added my only stonie corals, a bunch of what i believe to be hammers, about 7-8 branch heads. its in my 150g. anyway i have a natureef kalkwasser additive. is this what i should be adding? or is there something different strictly for calcium?
also with that coral / water ratio at what rate would i need to or expect to dose calcium?
thanks. sorry this is in the nano section
