So I just bought some carbon stones from edit cuz grasscity didn't have them. And I was wondering if anyone knows if I need to soak them on water for like 15min before using. Because I read somewhere someone said that you need to soak them in water for 15min when u buy from the pet store but im not sure if i have to for these Activated Carbon Stones - Online Shop
