Hi Folks:

I have a problem keeping this plant. I've bought it twice at my LFS.
My water is about 3 DH, and 3 GH, pH 6.7, 10 ppm Nitrates,.80 F. I
fertilize with trace, Excel, and other Seachem products. 2.4 watts/gallon
55 gallon tank. I'd love to keep it but w/in a couple of days the narrow
leaves start turning brown from the top on down. Perhaps I should trim it
first before planting and let it grow back?

Another quick question please: Which is better for a warm water tank:
Vallisneria or Sagittaria? Thanks for the help!
