Hello,
I keep collecting this matter from the substrate of the aquarium. This initially appeared when I started overdosing Excel to kill thread algae. The thread algae died and I think left this behind. The problem is that I keep collecting this stuff from the tank and it keeps coming back.
Is this because the algae grows and dies all the time? I don't see any algae any more for a long time but I keep overdosing Excel.
Maybe its my Azzoo substrate which deteriorates?
What is this anyway?
