It becomes toxic????
well i change it out every month so perhaps thats why it hasnt been a problem but i never heard its toxic before!
But im using the carbon because I just put two new pieces of african root wood in the tank and they are still leaching tannins plus i will be adding more wood in the coming weeks so for now carbon is a good thing!
