I have the rotala rotundifolia/indica in my 55. It grows like crazy. Have to trim every 3 -4 weeks. In fact next weekend. I use a Stingray also with root tabs, ferts and excel. No CO2 injection for me.
No problems, No shedding whatsoever. As mentioned it grows like crazy. I have replanted some of the trimmings all "OK", even traded some to my LFS. I have had to trim it again since the June pic and will again on Sat.
