This plant grows sooo fast that there are times that you just have to let it grow. I had to trim it twice a week to keep it from hitting the surface.
Some species you want to grow along the surface. They tend to propagate faster this way.
Some species you do NOT want to hit the surface. These have thick stems and once they break the surface, they start putting all their energy into Emerged growth and will shed it's leaves in the water.
