So right now the only filters I have for my tanks are the HOB kind I know they aren't the best but I'm not going to be able to upgrade them any time too soon. So my question is that if there is any kind if refillable carbon I can purchase for them or am I doomed to use the carbon in a pad type? I know it's not generally wise to change your media often but as to my understanding carbon isn't useful for more than a couple weeks help plz!
