| | Vallisneria and Sagittaria
I have several species of Crypts, 2 different Echinodorus, a very healthy Crinum, Hygrophila, 2 types of Java fern and many water lilies growing quite well in my aquarium, but Vallisneria and Sagittaria just will not grow. They have not died yet but they are, slowly, over 8 months. Good lighting, CO2 injection, fertilizer, pH 6.7 to 6.9, GH 6, KH 4 and temperature 80 degrees F. What are they lacking that the rest of the plants can do perfectly well without?
Gull darn it, in the last 10 months the 3 Cryptocoryne blasii that I purchased have become at least 50, my amazon swords are 18 inches tall and producing runners at a rate I can hardly keep up with, the Java ferns are taking over and the Crinum has 20 4 foot leaves and has bloomed twice in the last 4 months, but I can't grow grass!
