I ran 7.1oz of computer pins through 50/50 water/nitric with great results! Now that I'm filtering I'm finding that I'm getting this grey, clay like substance clogging up my filter. I filtered what I could but now I have this grey clay lump that has all of my gold in it. Maybe I need to dilute more before filtering? Just kind of frustrating and confusing all at the same time. Any advise or explanation would be greatly appreciated

Thank you in advance
