Honestly it looks fine to me. Do you have clean up crew? They should clear that up. That's a great looking sponge!

If you thing it looks dirty then blow it off with a small power head while your circulation power heads and return pumps are on and it’s even better if u have filter socks

Turkey baster and blast it. If it blows off great if not then maybe small sponges sort of thing. Directing a power head also could work.
