Thanks a lot for your answer.
Most of the plants are in the viv for over a month now, only three were added a week ago, but all plants have been processed before entering the viv.
I was actually more concerned that they weren't sturdy/rooted enough to withstand my frogs.
As for the water, it was just an idea that it could be beneficial to add tadpole tea into the water area, I actually never read it myself before.
I use distilled water for misting and treated water for the water bowls, so it doesn't lack minerals. I read you should never use distilled water directly with frogs. Is this wrong?
I'm not sure why my pics are not showing up anymore...
Just to be sure, here's the pic of the viv again
