I haven't added magnesium in the longest time and I realized I am out of my solution. I made it with epsom salts and mag flake in the past. I noticed the new disclaimer on the website this year. Is it still OK to use mag flake to make the magnesium solution if I am using the same bag of mag flake that I had a couple years ago?
