Some people here at Curezone have cured candida without taking care of their Amalgams at all. It is actually the case of shelleycat. Here is her forum: askshelly.com
I honestly think that heavy metals - and the consequent acidity of the body - is one of the main causes of candida.
Your metabolism has the power to chelate all the heavy metals, by drinking plenty and getting your mineral in balance. All the heavy metals will come out easily but slowly, all BUT mercury that is somewhat more difficult to chelate. Coriander chelates mercury and it is the option I have taken.
