Red algae on sand, please help with ID

[zmitty]

Hello everyone,
could you please assist me in identifying this red algae on my sand bed? My tank is approximately three months old, and I have experienced two phases of algae growth. Initially, I had diatoms, followed by green algae. Currently, I have noticed this red algae mainly on the sand bed. It does not appear to be slimy, so I believe it is not red cyanos? Thank you in advance.

Nitrate 7.0
KH 9.2
Phosphate 0.05

need more flow, it's treatable with cyanoRX and another brand I can't remember the name...I think it starts with Blue something

Agree more flow, and the other one (that I use) is chemiclean.

Cyano, common for young tanks, and older ones that get sunlight.

Thanks a lot guys! I will be adding an additional power head, I suspected one MP10 might not be enough for my Red Sea 170. Also thinking about adding some beneficial bacteria. I will give it a chance but if the corals start to get covered I think I will go for chemiclean.
