Trimming Vallis

[Superman]

Whats the best method to trimming vallis?
I find that its now at the water level and and seems to have created a film on the surface of the water.

Do I just chop it down?
Is it best to cut it at an angle?

trim it at the substrate mate, IME it never does well if you just cut the tops off.

So the leaves that have reached the top cut them right at the substrate level.

Try it and see. Depends on the Vallais, the ribbon ones that trail down the tank in the flow can be cut off at the water surface with scissors. I have a twisted one however that just melts or goes black at the cut if you trim it.
