There a couple reasons. One is that micro algae like turf algaes go much faster than chaeto so it pulls nutrients out of the water column quicker. Two is that turf scrubbers use a variety of algae so some can pull out nutrients at different n ratios. Also to answer the question about yellowing I've done both ways of cleaning the screens and haven't seen any difference in yellowing either way. Hope that helps some , gotta go back to work
