I am really cleaning my Eshopps HOB Protein Skimmer PSK-75H for the first time after about 4 months of use. I was scrubbing out some algae from inside and suddenly a small quarter circle plastic piece fell out. I can't figure out what it does or where it goes. Please see the picture below. Does anyone know what to do with this? I hope I did not break it.
