Is this Algae?

[christopher.lauwers]

I have this fuzz all over the top of my rocks and I think on the back glass but hard to tell. Seems my chocolate tang is picking it off but hard to tell and he swims and hides when I come by. Bigger hermit crab is going after it too. Snails no so much.

Tank is 8 weeks oldish
Stocked lightly
Have some frags in there with 3 xr15 blues at 60%
Established fuge need to harvest 2-3 weeks.
p03 .04
No3 1-5 … waiting on noys test to be more accurate. Just have api
Feed twice a day of Mysis shrimp.

not sure if this is part of the ugly phase or GHA… and looking for any feed back.

It's possibly GHA but could be something else. @christopher.lauwers Would you have a larger pic of the tank and could share with us your Alk and/or pH?

Got some more pics under whites hopefully you can see it.

Based on the look of the rock, I'm guessing something else is competing for the nitrates you're getting in the fuge possibly?

Running chato in my fuge now and it a pretty good size clump rotating with a Neptune gfo light going 24/7.
I would think the chato would put compete anything in the main display for nitrate? No?
