High nitrates?  Really?  I had never thought of this as a problem, since 
nitrates are food for the plants.  Do you know a scientific reason for 
this, or is it based on your personal experience?  Finally, what level 
should I try for, say 10-20ppm?

Dirty in what sense?  I do get pretty good clouds of dirt when I disturb 
the gravel, such as by planting, but there isn't a ton of stuff on the 
surface.  Also, observing the tank from beneath doesn't reveal a thick 
layer of black sludge, like I've heard of.

The Crypts were sold as C. wendtii (2 stems) and C. cordata (2 stems).  I 
know that part of the problem is the continual disturbance that the 
plants are subjected to by the fish.  I have partly rectified this by 
using a plug of plain rockwool to keep the fish at arm's (fin's :->) 
length.  The 
plant I think is a C. affinis is only a couple of day's in my possession, 
so I don't know if it will melt.  It is much bigger than the wendtii's 
I've seen and does have the veins prominent on the top of the leaves 
which you mentioned.  Anyway, it has the "look" I was wanting, so I'm 
going to run with it :-).

Thanks for the help.
