Do I need to remove my Carbon Filter?
I have a Fluval Spec V, 5.5g tank that has a 3-stage filter system. I am not sure what that means but it has a foam filter block and a space for Carbon filter, and space for BioMax bag thing. So I read that the carbon filter will remove toxins but may reduce the CO2 level which affects the plants growth. So do I need to remove the carbon filter bag?
I am still reading and learning. thanks.
