IMO, I would do a large 80%-90% water change and do a very thorough cleaning, ie clean filters, gravel vac where you can, remove as much of that stuff as you can, and reset dosing. Also, you do not need to toss old filter material, so long as you clean it to prevent reductions in flow and its not falling apart.

How long is your lighting cycle? Have you checked nitrates recently?
