Lowering alk

I ask as I'm curious to know how much the Chloride levels increase as Alk drops

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.
