Is the H. zosterifolia getting ahded at all. I noticed you have placed some floating plants in the tank. In my experience, if it gets shaded much at all, the leaves turn blackish grey and look horrible.
I have had this plant be either a true "weed" or just languish along. Unstable CO2 levels seem to make it look the worst. I have grown it with good CO2 and without any CO2 in the past. The only time I get the nasty leaves is when I either let my CO2 levels drop off or let the NO3 get too low.
The stems I gave you weren't in top condition
It was severly shaded in my 30g if you remember and some of the plants were black and others were disintegrated already! The ones I gave you may have already been on their last leg when you got them, but hey, the price was right
I think they will pull through as long as they get enough light and nutients.
