Water flow will kill it. Direct as much flow you can at the carpet. HC will stay put if it's rooted but Utricularia in general melts in high flow water. I discovered this when I hung Utricularia Vulgaris, which is more sturdy than this one, on my spraybar. It melted and detached from the bar.
You will most probably spread the damn thing as there is nothing but manually removing it you can do. You can, however, make a mesh cage of some sorts to have it caught in it. You mince it with flow than collect the remains in the mesh and take out the mesh.
