In the end for me, It was a higher pH, Very little feeding after the blackout, Very low light schedule, And I used a siphon to suck every little bit of it that I could find out every time I saw it over a period of two or three weeks. The siphon went from the top tank to the bottom through a couple of filter pads. It was really hard because it came back every 20 to 30 minutes. And there were times when I could not get to it while at work Or out. After the first week it started coming back slower and slower. Until after week three it just stopped coming back.
