Neon orange algae ID

[andresvallado]

Hi all! I recently had a massive GHA or BHA? that I´m trying to control. But I noticed a neon algae between the Hair algae. I don´t believe its coraline since it seems hair-y like. Any ideas on what type of algae this could be?. My tank is a 15 gal running for 4 months now. Corals seem doing well (photos attatched) despite the Hair Algae bloom, all have extended polyps and I´ve noticed growth on most of them. I wont post Phosphate and Nitrite parameters due to GHA bloom giving false readings

Parameters:

Salinity: 1.026
Calcium: 460
Mg: 1,370
Alk: 8.4
PH: 8.2-8.45
Temp: 78º
Refugium with Chateo, 12 hours inverse lightning schedule
Light: AI Prime 16 running only blues for 8 hours (2 hours ramp up, 4 hours peak light, 2 hours ramp down, 320 par on top 75 par on buttom)
Inhabitants: 2 Fire fish, 2 clowns, 1 urchin, 5 cerith snails, 5 bumblebee snails, 10 hermits, 3 emerald crabs, 2 Nassarius snails

Is cyano a possibility?

Is cyano a possibility?

It might! it is in a high flow area though! but it could be. Phosphate is 0; don’t know if it’s fue to the algae or really 0. hoping to get the GHA bloom under control. Once I get rid of GHA I’ll test again for phosphate; but it surely is a possibility
