Well as I'm getting more into the hobby I'm getting to the point where I need to dose. I picked up alk,cal and mag from a shop three weeks ago. There bright well and in the powder/dry form. I was wanting to know how much you'd dose on a 90 mixed reef. I have a little bit of everything LPS,SPS and softies. I would also like to know what color to look for in the Red Sea test kit the reef foundation. All input would be very helpful. Also what should I mix them in. And what's your thoughts on the apex doś system?
