My tank is beginning to get overgrown, and it is in desperate need of a trimming. Specifically, how do you trim Vallsneria and chain swords? Do you just cut straight across the tops? Also, will the plants grow back?
From what I've read, Val's are quite forgiving with trimming. Most people cut the leaves at an angle at what ever height they want, and the leaf will repair itself and be just fine. Not sure about CS, maybe try googling it.

trial and error for alot of it, try one way with some try another with some others and find out whatever works best, your said you were over grown, so if something goes wrong one way then you will still have others....
