Brown Snot ID please

Not sure what this stuff is and how to fight it. It is only on the rock work and not on the sand. It siphons off easily just a pain in the neck doing it every day.
PO4 0.03 NO3 5.3
Thanks

Chrysophytes @taricha ?

 

[taricha]

probably. Here's my criteria...

Signs of chrysophytes:

blobby gelatinous mucus
sometimes mucus so strong it holds shape out of water
light brown/tan/gold
under microscope, embedded in thick mucus
cells spaced out in the embedded mucus
cells are super tiny
cells nearly spherical
cells totally motionless

If the OP confirms that the cells are essentially motionless under the scope, then I'd feel more confident.

No motion at all. This all started when I was feeding a phyto that was sold to me as isochrysis galbana. At that time I was also feeding a supposed phyto blend too. I have since tossed the blend and the iso and am just feeding tetraselmis.
Thanks for the response!

This potentially explains the growth in a pair of my 0.2 L aquaria, little balls that formed a gelatinous or snotty cyanobacteria-like tuft.

It's pretty distinctive stuff. The microscope usually confirms the eyeball appearance.
