Changed 8 gallons of water last week, getting ready for another 5 gallon water change for tomorrow. I scrub the lr before I change the water. lights are off 24 7. Cycling since January the 14th. Now I have GRAY substance laying on the sand and on parts of my LR . Any idea what this is ? Tried to take picture but did not show up very well. sorry
