I am not sure what it is now, But my instincts are to siphon stiuf off the sand bed asap with the water changes
My concern is that it may have been something unnatural that made its way into the tank and is settling,.
Add to the confusion, I don't trust my eyes to distinguish between hues unless the LEDS are on all white. Gray may not be gray under different spectrums. (just take any coral out of your tank and wonder what happened to it and how did the brown stick get in my hands.
