Hardware stores used to sell a product called SenSafe Water Metals Test Strips, they did a lot of the ones that you would be worrying about. Thing is, you already know you have a problem. Water changes will get some of it but anything living in there will have taken some of it up and will release it over time. You could use a metal absorbing/adsorbing product and leave it in there. You can test for silica levels and see if they are insanely high.
Best bet for short term is a couple of 50% or larger water changes over a few days.
