Cool, thank you! So I take it Co2 isn't needed with my plant variety and fish in the aquarium then?
CO2 is the most critical component needed by plants and cause number 1 for algae and dying/not growing plants. Sometimes, given low light certain low demanding plants may get enough from the natural occuring CO2 in water via fish waste/respiration/organic decay in the substrate/surface movent(gas exchange), etc.. but in most scenarios these are very low levels and it all depends on the individual tank and the rest of the factors whether this will be enough. One can experiment. The lowest the light, the less demand for CO2.
Some plants are capable of extracting carbon from different substances so they can survive in low dissolved co2 enviroments because of that(like vallis for example), but all would prefer not to and would grow way better and nice with dissolved co2/injected co2. There's a different way to supplement CO2, via liquid carbon but this is an algecide and it also can have the same damaging effect to certain plants like vallis. It's not nearly as effective as injected CO2 when it comes to rate of growth. Certain high levels of CO2 and liquid carbon can be toxic to fish and even more toxic to inverts. The most sensitive species would need a slow increase n order to adapt to levels of these, taking care not to reach the upper toxic levels at which fish will start hiding/refuse to eat/gasp at the surface/die, etc...
All plants would also need nutritients, macro being called macro because plants need them in macro amounts
and micro, or otherwise called trace fertilizers in trace amounts.
The light that comes with most tanks this days is in most scenarios more than the plants need/can manage with the current amount of CO2.
However, the plants you have are very low demanding as far as CO2 goes, so you can just get some fertilizers and dose these for a start. If you start seeing structural damage to plants like holes/melting/withering away, etc..then you also have a co2 shortage and if not addressed, the tank can get covered in algae. Good/even flow around the tank also plays a role in distributing the CO2 and nutritients, so sometimes this is the cause of problems if the rest of the factors have been covered.
