So I can tell you from my experience that frogspawn are pretty sensitive to all swings. If this was an alkalinity swing, yours would be closed up or receding. I'm not seeing that in your pics. Do you have two lights on that tank? Like two individual units that are paired? If so, how close together do you have them. If too close, it creates a large overlap which can increase intensity in those spots. For instance, if you think your at 30 intensity, you may actually be at 45 due to overlap.
Hey,
I have 2 radions 30 and they are well spread and positioned. I also used my par meter to make sure that it wasn't wrong.
They are mounted 10 inch from the water
