Ok this is really weird but I need to know if using Calcium Chlorinate to balance water hardness can can cause my magnesium to tank? I have a condition that causes me to have electrolyte wasting and I got a salt water pool t help me with that. It usually causes me great relief and tops off my electrolytes but I was instructed to put in the calcium C. a few days ago and then I swam in it 24 hrs later and afterward within a few hrs was in tremendous pain. The pain I get when I run out of magnesium and my muscles seize up, especially in my back. Is this possible? That it caused me to lose my magnesium? I'm having a terrible time getting my magnesium back up.
