alanmin4304 Posted November 2, 2007 Report Share Posted November 2, 2007 You can leave it and it will grow along the surface. Only problem is it will block the light on plants underneath. Quote Link to comment Share on other sites More sharing options...
nemines Posted November 3, 2007 Report Share Posted November 3, 2007 if you let it grow across the surface it can also hinder water flow and you'll end up with some surface film, not good for oxygen exchange or light penetration. Quote Link to comment Share on other sites More sharing options...
