It's both. There are definitely stains but also loose iron that i've been vacuuming up. My guess is that since I added the clarifier which clumps stuff together (right?) it made the iron particles sink to the bottom. That's fine, I don't mind vacuuming. I took the day off of work today to finally enjoy it, and just got back inside (8:40pm 
). Super happy with everything, and I couldn't have done it without everyone's help.
