So I have noticed 2 kinds of algae in my tank recently.

The first is this algae(?) I have had on a few frags over the few months and it isn't anything too crazy but just curious if anyone knows what it is? It is mostly on the base of my Euphyilla's. It's pretty short in length and never gets any longer then about 1/4" - 1/8" and is generally only ever in the shape of a V with two distinct stems. Corals don't mind it and are happy as can be. I dipped (CoralRX) and scrubbed the plug with a toothbrush before putting any of my frags in the tank.

The other algae looks like White Hair Algae? Its thin and stringy but it's white -- I am running Bahama Oolite so it could be small sand particles that get suspended and trapped hence the white appearance that has popped up around the tank.

My nitrates (20) and Phos(0.12) are a tad high and its a 15g AIO FluvalFelx that's been up for about 4-5 months.

I have a pretty small CUC (2 Nassarius, 1 Mexican Turbo Snail, 1 Turban snail, and about 4 small blue legged hermits) and then a skunk cleaner shrimp and a fire red shrimp. Other then that I have a clown pair and a ywg/pistol pair and way too much coral. All this will be moving to a 50gal in about a month and this 15g will become a QT tank.

Any more CUC that I could add to naturally combat this? Not the biggest fan of chemically altering the tank unless needed.

Side note -- anyone know if that's zoa pox on my Illuminati's? They have been like that for about 1.5-2mo and seem happy otherwise. The white bumps aren't raised at all like other pox pics I have seen.
