Many metal test kits are available for the home and commercial pool market, but the vast majority of these only measure the free form of dissolved metals. Dissolved metals typically exist in two forms: the free form, and the complexed or... sequestered form. It is essential that both forms are measured when determining the total metal concentration of pool water. Make certain the metal test kit contains a releasing agent that is added to the water sample. Generally, common liquid dropper or strip format tests involving one-step procedures only measure "free" metal concentration, while two-step testing procedures measure "total" metal concentration. Periodic Products' EZ-DX® Digital Pool Water Test Kit easily and accurately measures total copper, total iron and manganese levels in pool water.
