Aquarium Advice FINatic
I have a 55g tank with an assortment of plants in it that seem to be growing okay but I'm not sure if they need co2 or not.

fort384 said:To answer your original post, yes, all photosynthetic organisms (plants included) require CO2. CO2 occurs naturally in your tank since the water will remain at equilibrium with the CO2 concentration in the surrounding air. I am going to assume you are talking about CO2 injection though
There are very few aquatic plants that we commonly put in aquariums that require CO2 injection to be healthy. Even most what we call high light plants do not require CO2 injection to be healthy. Your lighting and your plants definitely do not require CO2 injection. I would certainly not put swords on a list of plants that require CO2 injection.
One of the big reasons we inject CO2 in a high light planted tank is not only for uptake for the plants, but because it helps the plants uptake nutrients more quickly, which in turns help limit the growth of certain types of algae.
