Hey was looking to get this stringy algae. Defeated Dino’s with a uv a month or so prior but this I believe is agitating the zoas and gsp.

Alk 7.5
Phos .18 went up .1 in 2 weeks
Nitrate- down to 1.6 was about 7 2 weeks ago
Salinity 1.026
Calcium 400ish

Tank is about 14 months old

Ostreopsis dinoflagellate

Ostreopsis dinoflagellate

That’s what I was figuring. Can’t figure out how to get rid of it since the uv killed it all the first time. Nutrients seem to be okay?

Sorry, I cannot offer you help with the dinoflagellate problem. I do want to point out that all cures including UV are unlikely to be getting rid of the dinoflagellate from the aquarium.
