Thanks for the insight! You emphasized that you dont use calcium with D3, why is that? I know it's not advised to use with UVB but I wasn't using UVB before, which is why I was using calcium with D3.
My toad has since recovered and hasn't shown any other issues since this incident. I've only changed a few things- switched to remineralized RO water (so done away with reptisafe) and began using UVB a few times a week. Still using my dusting schedule, I feed in the enclosure but I do tong feed so I know my toads are getting everything.
