When I did my weekly tank clean and sand vac, I disturbed a lump of stuff amongst some small stones, which looked exactly like a small piece of feta cheese - a crumbly and white lump, about half cm long.
Any ideas what it is?
I know I did'nt put it there.

Oh well, I'll change a little more water tomorrow to be on the safe side.
