Why Aponogeton turning brown?

[awungfoo]

Can anyone help with why my new Apogoneton leaves are turning brown? It was a recent purchase and the bulb is hard. It is already setting roots and there were 4-5 new leaves sprouting. I was away for 5 days and when I came back, all the new leaves had grown very tall and started turning brown in the center and dying off.

Thanks for any insight

Try to scrape away the brown stuff. Sometimes it is some algae that kills the leaves. I had that brown stuff on my swords and killing off some leaves till I scrape off the leaves and excel/fert dosed it.  If not algae. Someone here might know what it is.

It may have produced a flower. Sometimes Aponogetons send up a flower to reproduce, then they die back and go dormant for a month or 2, then regrow again. They are pretty fun to have in the tank as one do you realize, awesome it's back!
