I have some algae on my works and I can't seem to ID them. I had a really bad Dino outbreak going but it's getting a lot better and they are pretty much no Dino's on the sand anymore however I have this very stringy algae on my rocks are these also Dinos? or some sort of other Algae? Any help is really appreciated my tank is about 4 months old now. You may need to zoom in on the pic as the algae is quite stringy and it kind of brownish in color.

I don’t see any brown string growth but there are all sorts of green algae colonizing the rocks. It could be the start of green hair algae and/or cyanobacteria. If you can get that stuff under a microscope and photograph it, someone will recognize it.

It's normal algae that is supposed to grow in a new tank.

What are your parameters?

Salinity: 1.028
Nitrate: 0ppm (Working on increasing this via feeding more + dosing)
Phosphate: 0ppm (Working on increasing this via feeding more + dosing)
Temperature: 82F (increased to tackle the dinos)

-Why so salty? Should be 1.025-1.026

-If you have algae, then do not dose nitrate it will fuel the algae. Don't overfeed, rotting food fuels algae, feed small amounts several times per day, no food should go uneaten.

-Do not dose phosphate if you have algae problem, it will fuel algae.

algae is consuming the nitrate/phosphate, thats why you have zero reading.

-With fish and corals in the tank, you should not increase the temp to 82. Don't discomfort your inhabitants over algae.

Beautiful picture!

I see two types of filaments. The wider filament looks like a filamentous algae, i.e., a hair algae. The narrow filament, I can’t make a guess. The gum drops scatter all over could be a cyanobacteria.

Thank you! I guess in this case algae is a lot better then my previous dino's so I think I will just let them play its course and slowly do water changes
