Aquarium Advice Addict
The other day I heard that carbon in a planted tank can absorb some important nutrients for the plants. I have an aquaclear 50 running biomax and the sponge. I just took the carbon out. What else should I add? Should I add another sponge or biomax? I would prefer to add something else, but not sure what else I could add. Any help is surely appreciated! Thanks!!
