Aquarium Advice Newbie
I was going to add a power filter to the marine aquarium I'm just starting however I was told not to add the "white rock" filter media to it, just the carbon and sponge. (The name of the "white rock" is on the tip of my tongue but I can't recall right now. I believe it is the amonia remover???) Is this fact or fiction? ...the part of adding it to the system.
thanks...
