I've used the top portion of a Styrofoam drinking cup for feeding and it floats well.What could I use to make a small floating ring for a 5 gallon? The salvinia roots are growing way longer than I thought they should, making the tank very dark.

I've used airline tubing.

You could get a small styro foam ring from the craft store. They come in white and green. You could wrap the roots around it.
