I dont have a reactor (not enough space). I use turbo Calcium. It works great, I can keep my calcium levels correct, with very little effort. I dose Magnesium, via kents Tech-M. I have incredible growth, on all of my SPS and LPS. When I first got the monti, it came damaged there were little pieces broken everywhere. I put most of them just laying on the rock. Big Mistake In
five days all had hooked onto my rock, now many that were 1/2" are two inches. All of this happened in about a month.
