Is this dirty or what??

Not sure what is infesting my tank. It appears to be "particulate" but regular cleaning and filtration won't get rid of it. Removing it manually with syringe and tube, but not making much progress. I do have some white algae that I'm treating with Algaefix. only parameter not "perfect" is nitrate, but that is relatively low ~1.5ppm (way more yellowish than orange test). PH ~7.8 salinity@ 1.026. 50gal, zoas, hammer, gps, number of h.crabs, 2 nessarius, 2 mater clowns. see photo/video

Really hard to tell from the images (sorry), and I can't view the video on my iPad. Hopefully someone else has some eagle eyes...?

It’s not algae, but appears to be a type of sponge. I recommend getting a positive ID before dumping anything into the tank. These are beneficial.

Are you talking about those little white things on the rocks? Hard to tell what they are exactly but IMO it's nothing I would worry about.
