I manually remove, it helps but the stuff comes back.
I also have a Foxface. I think he eats it. I mostly have it in places he cant get. Emerald crabs also eat it, I dont have those.
Try not to pop bubbles. It contains spores. I turn off all pumps. I use a length if small diameter rigid tubing, then soft tubing to a bucket. I vacuum as I pull it off. Its not fun, but I do it most every water change.
My outbreak started when my nitrates got over 10. I have been reducing those. Hoping it subsides.
