Help needed: im trying to grow some Wolffia duckweed, and the enclosure i have made for them has been hit by something. It appears in the water as white fuzz, and appears to grow between the duckweed, tying them together. I droppered some of it onto a slide, and put it under the microscope. It came out as this fiber. Is it a cyanobacteria? Is it harming my plants? If it is a group of cyanobacteria, they will go away once the duckweed thoroughly shades the surface.
