Need an ID on this type of algae any help?

[bendy]

Hey the fellow reef enthusiast's,


I have had my tank running for currently 4 months now and when recently doing a water change I notice some green algae covering the surface of the live rock, I can only see this when the light is off.

My nitrate levels are sitting at 0 ppm

I currently have phosphate pads in the tank with carbon also

Any ideas on the best way to limit the algae? I have included pictures.
