Algae with air bubbles on sand

[Densepy]

Does anyone know what causes this type of algae & how can I make it go any? Thanks

Much more info needed as there is no one way to do it.

Add these things to your profile.
Tanks age ,size and amount of LR and LS?
All equipment used?
All the readings you can test for?

While waiting for the answers to those questions, I'll throw out a guess: You have Cyano and should increase your flow.

Notice that it only collects where you have dead spots.

What are you're nitrate levels?
