Can I take a clear glass of pool water. Than add a lot of shock too it. Will it change color if I have metal/iron / minerals in my pool ? I never have my pool at shock level so how would I know

If you suspect you have iron in your water (or possibly some other metal), why don't you have it tested at a pool store?
