Ugh I thought I would never get rid of that stuff when I had it. And I did so many things to fight it who knows what actually did the trick. I kept it mostly controlled by a combination of manual removal of the worst of it, more consistent fertilizing of plants, excel and h202 spot treatment. It was still cropping up at that point but it was pretty minimal.
Then my local fish shop got in Siamese algae eaters and Amanos. I added both and it wasn’t instantaneous but it did finally go away and I haven’t seen a single tuft in months. I think perhaps they didn’t like eating the old mature bba but I’d see both the SAE and the shrimp eating the smaller young tuffs and anything that I had spot treated.
Eventually it just didn’t come back.
