from my noobie experience and knowledge.
is always a good thing for plants but not a needed in lower light setups, I believe you will start needing co2
after 2 to 2.5 watts per gallon. if your going low light or medium light do less frequent water changes to keep co2
levels steady and not fluactuate thus keeping BBA in check. you might need ferts depending on how many plants but I would say it is always better, something like- Potassium Sulfate, Mono Potassium Phosphate, Potassium Nitrate, CSM+B Plantex. maybe get a test kit that reads phosphate is good to have.
regarding the filter I believe that is fine since you do not have co2
, this might keep the co2
tank levels with ambient levels, but once you start adding co2
in the tank less movement is better on the surface of the water.
you might need flourish excel to dose some sort of carbon.
I thank you all for your attention and time!
