Help with Hair Algae overtaking Zoas

[BoxInSox]

Hi All

My tank is just over 3 months old - 53 gal total volume Red Sea 200+

I've had a sudden spike in hair algae, and it's mostly concentrated on my rock work and taking over some of my zoa colonies, etc that are glued to the rock work.

Current testing with Hanna checkers show Phosphates at 0.05 and Nitrates at 10.8. I know that neither of these are high, but it is out of balance with the 16:1 ratio I've read about by a lot.

I just run a filter sock and UV skimmer in my sump for now, along with a bag of carbon.

Another unique thing going on is that I'm currently going fishes due to a velvet or brooklynella outbreak (have about 4 weeks to go to hit the 77 day cycle to reintroduce fish). I do have various snails, a cleaner shrimp, emerald crab, tuxedo urchin, and conchs to help keep things clean without fish.

So my questions focus on 1) Are my phos and Nitrates out of balance, and should I address that first, and 2) would a chemical approach like Vibrant or something be warranted here, to try and save the corals?

A few pics are attached for reference.

Thanks!

1. Your nitrate and phosphate levels are fine.
2. I wouldn't touch Vibrant with a 50-foot pole (people have had entire tanks wiped out from its use).

I’m not 100% sure if I’m convinced it’s hair algae or possibly something else

If you wanna wait it out pop the frag plugs off thr rocks and dip them in h202 it will kill the hair algae and keep them on a rack till your rocks clear up.

There's definitely *some* hair algae in the images.

Well I would make a vacuum line for air hose and add a stiff end to it. Pull off the hair algae the best you can once a week.

I am feel this might be part of the tanks cycling and the war for food and stuff is happening.

I have no silver bullet.

I have been fighting hair Algea for years and it comes and goes.
