HOB Mechanical Filter

[Oscar]

I continue to have algae and cyano problems. I am doing some pruning, installed new lights (heavy to blue), reinstalled my UV sterilizer and continue to stir up my detritus. I also have a reactor with carbon and GFC.

One thing I have not done is mechanical removal of detritus when I stir it up. Any suggestions on a mechanical HOB filter for this purpose? My idea is to only turn it on when I have stirred up the detritus and turn it off when the water has cleared.

I do not need to add carbon to the HOB so could I add more floss in addition to the existing mechanical filter?
