Jim I have the AI Vega Color and wish I got just the AI Vega Blue. The Green and Red lights are only on a few pucks and it puts RED/GREEN/PURPLE spots in (2) places in my tank. I turned them down to 5% also because it caused a disco effect in my tank. JMO. I am getting a few Brown patches on my sand bed that goes away at night too. I am running my Blues at 95% and White at 20% because i like the blue look as well. I am playing with the lights to see what is causing the brown bloom during the day. I heard that Red and Green can promote algae growth? Phos and Nitrites at 0 so I am thinking lighting is the cause. I am running the lights in Easy mode and they start at 9:30 AM and go off at 9:00 PM with a 1:45 ramp up and down. I also have 1% Royal Blue all night for moon light. May be just too much light.
