Medium light dosing
I currently have a low light, low tech tank. However, I'm wanting to up the lighting to medium. Mostly because I want to carpet the tank with Staurogyne Repens. I'm planning on hitting the S. Repens with 45-50 PAR and no CO2.
My questions are what do I need to do? Is that even possible without CO2? Do I even need to fertilize without CO2? Should I only dose micro or macro or both? I don't mind waiting a year or two for the plants to grow in at all either, so if time is all I need, then I'm fine with that too.
