My carpet of UG and mini micro swords are getting pretty thick.  I was told that if they get too thick, its hard for water to follow through them and it will be an area where bad bacteria will start to develop.  I was told that cutting out entire patch of the carpet is the best way to thin it out.  Here are some pictures of the “thinning” out.
