I have some Limno Aromatica in my 75 gall with 260 watts of flourescents, CO2 injection, dose excel daily, and EI dry ferts dosing. I had about 7 or 8 stems and they were literally growing out of the tank. So I just cut them off 3-4 inches below the water like I do for my rotala. The remaining stems were constantly losing leaves over the last couple of days and didn't show any signs of life (new growth, new branches, etc). So the ones that were really bad are gone, but I still have 2 smaller stems I did not have to trim. Any suggestions on what to do next time?
