The parameters are on top of the Red Sea coral pro salt. I think cal is 450, alk is 12.2 and mag is 1350. But that salt is used for growth. I test my freshly made water and add the big three to match my tank parameters. That's how I keep my tank stable. But then again I'm using the Red Sea coral salt which those parameters are lower than the pro salt. Also the parameters for the coral salt are for colors of your corals. I found this out the hard way and was ending up with your same parameters until I talked to the rep of Red Sea. Just giving you a heads up.
