Carbon

[shockshockshad]

I am going to add a lot of plants to my 30 gallon tank with this habitat. I have read that carbon in filters removes fertilizer. Well I have a penquin filter that the mechanical part is the same as the carbon. It is a plastic thing with mechanical stuff all around it, and carbon in it. I can't take it out, or else nothing is filtered. It also has a bio-wheel, so there is biological filteration in case you are wondering. I also have an aquaclear 50, but I can get the carbon out of that. And also I have a tetra filter for my hospital tank, which is a filter bag full of carbon. How do I remove it? And don't I need it, but I can't have it with plants! I'm confused!

Leave the carbon in the tank for a few weeks, it'll soon get exhausted and stop taking in nutrients. Just don't replace it.

FYI - there is an interesting article re carbon and nutrients in my sig.
