No flow on the top of the water so it is not pre skimming as needed. Get some water movement up there and cut the lights down for half the time over the next two or three weeks. Then slowly add the time back each day.

definitely need more water movement

NOTHING
need surface agitation to get good gas exchange.. also this will eliminate the slime
As everyone has mentioned, need more surface movement. Also, this appears to be an AIO (All in One) Nano, with the filtration in back. Is the water level in the back lower than in front? If not, it'll limit surface skimming. The level in the back chambers needs to be lower than the display level.
