Hi guys , couple of weeks ago i brought Radion xr15 blue for my 30*18*18 pennisula style tank. i use to run it around 80% intensity . week later i have noticed green algae growth on bottom glass as well as side glass. my tank placed in indoor courtyard area and im getting lots of diffused sunlight trought the roof (UV cut acrylic sheet ). my tank nutrient levels are
extremely low according to salifer testkit (no3 = 0.2 , Po4 = undetectable) . im running biopallets in my AIO sump. SPS colors are mostly brown except the green montipora. what you guys think about this issue ? is it something related to too much light ? if so how can i schedule my radion to work on this condition .

The sunlight is the cause of the algae. And the algae is the cause of your low nutrients imo. Is blocking the sunlight an option?
