Co2 with newt?

[Daimler]

I have an acquarium with lots of plants and i want to buy a co2 system but im afraid that the co2 can kill the newt (pachytriton) :sad:
i found Carbo Elixier Bio, it is liquid carbon without chemical additives and the shop say that is a valid alternative to the co2 system, someone use that?

Found this post where the guy used a carbon supplement in the water with very sad results.

I am very wary regarding what i add to my water. Even though I have a well planted tank I don't use ferts, I just invested in full spectrum lighting. The plants have responded well despite the lack of co2 or fertillizers.
