Can you tell me if I had good water from another tank I planned to start up with, but something went bad so now the water is still in the plastic bag.After sitting like this can I still use this to cycle a new tank ?

No, the beneficial bacteria live on the filter media, and substrate and ornaments. the water does not contain enough to be of any use. you might as well use fresh water.
