Green algae on glass and rocks

Hi,



I'm running a reef tank in a Innovative Marine 20 gallon since June 29 2019 and I'm starting to have green algae.
My nitrate and phosphate are both at 0.

I have the stock return pump, a MP10 and a IM Nuvoskim DC Protein Skimmer Desktop.
My filtration is, Chemi pure blue and purigen into 2 media basket on each side with some AquaForest life bio fil and 2 filter pad.

I have 2 AI Prime HD at 8 inch of the water level.
What can be the cause of that because this is the first time I'm having green algae like this.

Here some photos of the tank and my light schedule.
