| Re: How do I test for these?
Hey Orb,
Not sure if I understand your exact question but as far as I have noticed, phosphate and calcium test kits are usually easy to find and I know there are test kits for magnesium and iodine but I can't recall seeing one for strontium...but that doesn't mean they don't exist. I am not sure how many people actually test for magnesium or iodine on a regular basis but I can tell you that I have made it thus far without them. The phosphate and calcium tests are pretty handy IME. |
