Lighting too much or too little?

Mine (and my Red Cabomba for that matter) is very "leggy" i.e. long stems
with big gaps between the fern bits. All my plants grow like mad anyway but
I am beginning to wonder if in fact I've got my lighting a bit wrong. I am
wondering if there is not quite enough of it which is why the plants are
stretching upwards towards what light there is.

I doubt that's the problem. "Leggy" Cabomba (long internode length) is a
common, even in high light tanks. In fact, IME, it's more common in high
lighting. It grows a lot bushier in my moderate-light, non-injected tank than
in my high-light tank, I think because it grows slower.

One thing that can help is to never "top" Cabomba. Don't just chop the tops
off when you prune. Instead, pull out bottoms and re-plant the tops. That
helps a lot in keeping it bushy.
