I assuming a Ca of 450 ppm/ Mg 1400 ppm is good for SPS. My DkH hovers around 8( a bit lower) which is required for Ultralith program. I run a Calcium reactor and have a lot of rock in the tank. I am always interested in how a person who gets a tiny frag can grow into a monster within a year. "Marie's" tank comes to mind. I do realize some corals grow faster than others. I was thinking high DkH and Ca may aid in Ca uptake by Acros. What are they doing riight that I am not. I guess I really need to see someones tank (locally) who has been raising(growing) SPS successfully.
