RE: [APD] RE: plant filters/removing NO3

There are several species of water sprite, I'm assuming you are referring 
to Ceratopteris. From what you said it sounds like C. pteroides might be 
the species of choice. I have noticed in searching for information on these 
plants that they are often suggested for soft, acidic to neutral water. 
Would there be much of a difference between species? BTW, not being 
familiar with water sprite I got what is locally sold under this name, 
Hygrophila difformis. For some reason I had never liked it much but now 
seeing it in the tank I think I'll keep it.
