If its not one thing its another

Ok folks how do I get rid of this alga. It turns brown when the lights come on. The tank is 8 months old.
If it is not algae, still how do I get rid of it.
Tank parameters are below:
Salinity 1.206
Nitrate 2-5ppm (hard to tell with salifert test kit. I refuse to use my Hanna test)
Phosphate is 0.08 (not sure if that high enough to cause this alga)
Alk: 9.3
CA: Ask me when my Trident returns from Neptune
Mg: Ask me when my Trident return from Neptune

That looks like brown hair algae to me. Your nitrates are ok but the PO4 is a little high. Because the algae is consuming nitrates and phosphates, my guess is your numbers are even higher. I’d remove as much as you can by hand on a daily basis. Also, you could turn off the lights for a few days. Most corals can handle that. You’ll need to figure out how the PO4 rose so you can correct it. Over feeding or something dying in the tank are the usual suspects. I’d do some water changes to bring your numbers down. What do you use for nutrient export?

I have a skimmer, I use carbon, I do water changes every two weeks. I stopped using my gfo because my po4 was really low at one point I guess I can bring it back online.

Do you have a refugium, your nitrates look a bit low to me but I am not a fan of low nutrients?

Let’s ask the #reefsquad. I’m sure they can help!

I would do manual removal, feed less, and maybe set up a fuge. Also water changes would help like mentioned above. What tank size and stocking list?

Salinity should be 1.025 around that
Typo?

As mentioned, manual removal is best. Control feedings to help bring po4 down a bit. It is a type of hair algae. Quite common to be honest. I usually go with liquid vibrant. It takes around a month to clear up. Some have success with vibrant while others don’t.

If your tank is large enough add a Magnificent Foxface. I had a major hair algae problem which he solved. Now I feed him nori on a clip.

yeah that was a typo 1.026 is the salinity

I have a 210 but I also have 4 tanks Yellow, Blue, sailfin, Bristletooth. I feed twice a day. The first feeding is pellet and flake the last feeding is 2 cubes of something I try to mix it. Mysis and some type of greens.

I could try vibrant. I was going to get a CUC. My current Cuc is like 5 snails for a 210 lol maybe 4 snails and a crab.
