I'm trying to identify this algae that seems to grow faster than anything else in my tanks. I've been removing it mechanically but it grows back within a couple of days. See attached photos, any suggestions for what it is and causes/removing it and keeping it gone are welcome.
Also, it has showed up in all three of my aquariums, generally all at the same time. Amano shrimp don't seem to touch it, neither do the siamese algae eaters. I listed the PAR level at the substrate for each tank below their image. Appreciate any advice, thank you!
20 gallon (140 PAR at the substrate)
4 gallon (100 PAR)
75 gallon (90 PAR)
