i used to dose that. i switched over to the reef moonshiners method and haven't looked back since. my only gripe is not being able to figure out my consumption rate, or how much of my mix to use... i would hate to throw out the mix i made and start new but that may be the only way to bounce back before i lose anymore of my SPS.Yes, this is exactly why I decided to go with Redsea Foundation Elements to make it easier. I know mixing two part is easier but I just don't trust myself to get it right at the moment lol.
edit: i forgot to mention in my previous post that i also test NO3, PO4, ALK, CAL, MAG twice a week(Sunday's i use Hanna kits, Wednesday's i use red sea kit) as i am trying to get things in line(more specifically ALK).
