Also, most of us can't get our hands on Hydrochloric Acid, which is purer than Muriatic, and I'm concerned about the impurities present in MA. Muriatic contains ( among other stuff ) iron, so I wouldn't want to use it on a regular basis to adjust my mixed salt water.

No, I never tested Ca after using MA as I didn't think it was a concern. When I asked about MA affecting other parameters Randy told me that pH is the only concern.
