I'm bad with pictures, but my guess is cyano.


Too many questions....age of the tank, water source, frequency and percentage of water changes, tank details, bio-load.


A start is increase volume or frequency of water changes....assuming good RO/DI water source.

Looks like a new tank. Assuming that, you're tank is cycling. What are your parameters? You can cycle with lights out which will discourage algae growth.
