Daily- just feeding with either freeze dried shrimp or pelletsthe tiny dots of green are too small to tell exactly what they are.
Most likely just green hair algae (GHA).
The tank appears to be very new. The diatoms and algae are perfectly normal.
The diatoms will go away by themselves as the silicates they use are depleted.
The algae growth is dependent on the amount of phosphates in the system.
You can try to reduce the phosphates but don't get them too close to zero as this can other more serious problems,
Dino for example.
You can wait and see how much the algae is going to spread.
What is your tank maintenance?
