[APD] Re: why aren't my ludwigia Arcuata red?

[Paul Krombholz <krombhol at teclink_net>]

Any suggestions?
Having low nitrogen and the rest of the nutrients in good supply 
along with bright light is known to enhance red coloring.  However, 
with discus in a 21 gallon tank, I don't think that keeping nitrate 
low is an option. Just get the light as high as you can.
