Well, if you'd notice, he never said floating leaves, he just said the
leaves were growing to the surface. I have a couple crispus that grow tall
and spindly in one type of light, and short and wide in another. I think it
has to do with the amount of blue light as opposed to red light. I read
that in one issue or another here. I burned out a light in my 2.5 gallon
tank, and the lily type plant in it was never over 3 inches tall, but when I
put the light that came with the strip in as a temporary fix, the thing
started shooting leaves to the surface, and winding the stalks all over the
tank. I replaced the bulb, and things are back to normal.
