I was wondering if you ground high grade carbon,or charcoal,or ashes. Would one or any be uptaken by plants in aquariums? At least with carbon powders....its going absorb toxins for a short while. But does it in fine powder dissolve? Eventually?
Calcium or Baking Soda also? DO they supply carbon to aquarium plants?
