Yes with higher light the plants are more "active" thus needing more carbon(Glut or CO2
) and nutrients. Api CO2
Booster, Seachem's Excel, or Metricide14 ordered from Amazon are liquid carbon that can be used on your set up. You really wouldn't have to have pressurized CO2
. Then you need to dose Macro and Micro fertilizers of your choice. The liquid carbons also help fight algae that becomes more of an issue with higher light. You test for nitrates and phosphates regularly to know how much fert to dose. A good generic target is 10-20ppm NO2
and 1-3ppm PO4
. Also with higher light you don't need to have the lights on as long.(Algae) 6 to 8 hrs is usually enough. Here, a timer on your lights is invaluable. Good luck and welcome to the dark side of the force. OS.
