UAS, or "Unidentified Aquarium Stuff", from filter media, can get fish sick?
I'm re-starting my 10G quarantine tank. I bleached it, rinsed it, dried it, the works. I bought all new filter media for my Aquaclear HOB filter, and stole a 2-month old Filter Floss from my 36G Display Tank to seed the tank to get the fishless cycle jump started. 2 days into it, there is "gunk" on the bottom of the bare-bottom tank. Looks like old oatmeal, 2 piles, each about the size of a half dollar. There is nothing else this could be than from the stolen filter floss. I'm guessing this is old food, or filter floss flakes?
1) What else could this be?
2) (I'll of course clean all this out and toss the used floss once I'm cycled), but assuming a fish somehow ate this stuff, would the fish get sick?
