All plants perform photosynthesis to survive. During this process, plants convert sunlight, water, and carbon dioxide into food. Across the planet, indoor and outdoor plants absorb CO2 from the air, making it easier for us to breathe.
The pothos roots absorb nitrates and ammonia from the water. These substances enter the water through fish waste and fish food. In large quantities, ammonia and nitrates can kill fish.
Pothos is a trailing plant that produces attractive green leaves with yellow variegation. But these heart-shaped leaves can display many different shades and variegations.
