Can we use Ganga water to bathe the Deities when that water is actually Krishna’s own charanamrita?

From: Sridham Vrindavan Das

As a custom we usually use Ganges water in various puja activities such as abhishek ceremonies of the deities etc. I recently met few brajabasi from vrindavan & in a conversation with them, they told me that do not offer lord krishna water from the Ganges as this is his charnamrita , which flow from his feet to Lord shiva’s head then it is received by the mortals on earth , The brajabasi explained that Lord Krishna is only offered water from the Yamuna as only this is dear to him , please enlighten me prabhuji on this mater & perhaps share with us all some more information to this.
