I have a small 15 gallon wide tank and an aquaclear filter on the back. I
had kept a spot empty where the water falls out of the filter assuming that
some plants don't like heavy water movement. Is this true?

I've recently had to trim the hygros again and planted some on the corner of
the aquarium and needed more room: so I moved the ludwiga to the center
where the water flows down into it. I figured that the ludgwiga has pretty
stiff stems and thicker leaves than the hygros thus less susceptible to
problems with water movement.

thanx

Dave.
