Aquarium Advice Regular
So what's the consensus on using carbon in the filters? I have 2 aquaclear 110's on my 55 gallon tank. They just have the sponge on the bottom and the bio material bags on top of that and that's it. Should I be putting the carbon bag in between the bottom sponge and bio bag? What would be the pro/con's of adding the carbon bags?
