charcoal help

[morgan]

Charcoal will not remove 'hard' minerals, mostly organics. It helps for people that have too wet of substrate. Soupy substrate will eventually sour, which charcoal can help absorbing those compounds.
If you have proper substrate layers, it is not needed. Will it hurt? I don't think so...I've been adding orchid charcoal chunks to my mix since forever with no noticed affects to animals.

I agree with morgan that proper layering would be your best bet. my biggest concern with my terrarium and charcoal will be my frog accidentally ingesting it so I use a barrier (mesh or screen) to keep him from burying into it.
