I got a used emperor a week ago, and i went to the pet store and bought two cartridges for it. The cartridges contain carbon in the back, and i was thinking of cutting the cartridge and poring it out. I researched, and opinions on carbon in planted tanks vary. I use root tabs and will get metricide 14 in the future. Will it take the nutrients from the tank?
