Mg levels are around 1200 in my tank, so I thought I will raise it a little to 1300. Went ahead and purchased this "Therapy soak epsom salt" from grocery store. Now I am not sure if I can use this one. It has ingredients Magnesium sulfate, peppermint oil, spearmint leaf oil and rosemary leaf oil and obviously smells like it. Is it safe to add this to the tank? If not, where do I get some plain epsom salt that has just magnesium sulfate?
Thank you
