Sorry I just composted them after taking them to a doctor yesterday who called them poo pellets. But the orange ones were bright like turmeric with the tail orange also. They floated covering the surface of the water. I was shocked when my daughter said, Mum the diahreah came very forceful this time & this was a great surprise as result. The flat ones were translucent light green. Both types very hard. None of the green stones like first flushes were present. These were totally different. We were told to go on full moon night & we did even though we had an unsuccessful flush a week & half earlier. We got our best results ever from this. I think it had to of been the full moon. But will take on board what u said nether the less
