I have one Aponogeton Ulvaceous and various hybrid apon bulbs that have been going for about 4 years now. The ulvaceous has gone dormant and come back more times than I can count. I use 30 watts of CFL's for about 12 hours a day. No CO2 currently, dose with Flourish once a week.
A year since my last post (on the previous page of this thread), and an entirely different balance of plants. Who says Nesaea Crassicaulis are difficult to grow?
