It is realativly short, but can. Get long and stringy. It is smooth feeling. Some other bad types feel rougher. Not saying turf is good, unless you run it in a scrubber. All algae will help with nutrient reduction. Some are just difficult to remove from display tank if they get in there. Most people choose cheato because it does little if it gets in display. Calerpa can go asexual and stop growing and can be a nuisance if it gets in display. Only thing that may play a part is different algaes may emitt something to not allow other algaes to grow, though I have seen many different types seem to co exist. There are many forms of algae, if you keep it all out of your display , they will all take up something. I think you'll get mixed options on taking it all out at once. Ideally you'd probably want it out eventually, idk if it would cause issues. I'd think you'd want something taking its place.
