Help with these spots..

[Nano Saltyy]

Hello guys..!
I wanted to ask to guys what is this red stuff that’s started to grow on the rocks. The tank is newly setup and is 3 months old. The stuff that’s growing is not hard and it comes off if I rub it with my finger or brush. I have Vibrant Reef Cleaner with me, will it help me with this issue?
There is no large bioload in the tank, only 3 thin striped hermit crabs.
Current parameters are,
pH - 8.2
Amm. - 0 ppm
Nitrite - 0 ppm
Nitrate - 30 ppm
The lights are running for 6 hours only.

Those look like little spots of dinoflagellates to me. I have never used Vibrant before so I cant really comment on what it can and cant do. Dino's are a common algae and there are tons of forums on here talking about them and how to deal with um. I have luckily only had a few outbreaks when I was first cycling my tank and I just tried to syphon as much as I could out when I did my water changes. Hope that helps a bit.
