Not precise but I've ran the Red Sea Coral Colors and Energy in several tanks for a few years. I also have done so with BRS Cal, Alk, and Mag.. I always start out small and dose once per week and slowly increase slightly to where I feel I am getting good results and then I just stay constant... Currently my main Tank is getting 40ML of each once per week and its total water volume is roughly 300 gallons. I also have a 34 Gallon that gets 5ML of each once per week. I feel these numbers are sufficient for my intake and tanks. My DT is currently getting 170ML of Cal and Alk daily and 90ML of Mag daily. I also run high nutrient PH.04, and NO3 40-60, high alk (9.5-10), high light 4 radion gen 3 pro, 4 80w T5, high flow ( 3 MP60, 1 MP40, 2 Gyre 230s) in my DT. SPS dominant, fish overloaded, and decent zoa garden... with handful of LPS.
