This is more or less the same effect I've seen. I used to have meltdowns
every time I did a water change, before I injected CO2. After CO2
injection it all stopped. Now I get the occasional melted leaf (except
for this last occasion). I like the theory that the city ran something
through the water. One thing I didn't say in my first message was that
I'm not worried about the long term effects because, as Peter Konshak
pointed out, the rhizomes are probably OK & will throw out new algae-free
leaves in time.
Interestingly, you talk about cleaning algae off the leaves. I used to do
this in one tank, but never with Crypts because they're so delicate. Now I
just pinch off the offending leaves a la Dorothy Reimer (see her article in
FAMA 5 or so years back).

Nope. Nymphaea is one I've had a big total of ONE happy plant and
nothing but failures since. The stems either get nibbled off by the
fish, or the leaves die on their own.

This one will take a few months, because I got them as bare root rhizome
end-cuttings. All leaves melted after 2 weeks, but I'm looking over at
the tank right now and there are two new leaves at each node now. This
is a new species for me; I'll certainly update my progress with it.
