Gold Finger, I only tried cabomba once at the very beginning before I knew what I was doing, and it didn't last very long, so I can't really compare. But I have noticed my nitrates are much easier to keep under control lately, so the pennywort could be helping with that for sure. I'll have to try cabomba again sometime.
