Dinos? Cyano?

[QuiGonJay]

Any ideas as to this stringy reddish brown stuff that has popped up all over in the last few days? If yes treatment suggestions? It is getting out of control. I have a 28 gallon all in one and do water changes every other week. I run chemipure and puri general in the back cartridges as well as a small refugium in the other chamber. Nitrates near zero but I'm guessing it's a false reading and this stuff is sacking it up.
