Hi, I've got a JBJ 28, the AIO flow pattern/setup kind of confines me to a simple submerged screen right off the overflow teeth. I have a led shining right in the back at the 4x4 screen. Anyway, I've got 4 Steves Luxeon deep red (in a square), and one of the new true violet in the center. They are running on at 700 H LDD, dimming with Arduino analogWrite thingy (fast flashing not current dimming). Anyway, I've let my screen sit in the water 2 weeks without light, then 1 weeks at 20%, 1 weeks with 30% and now I'm on the 4th week at 40%. No significant growth on the screen yet, but the glass between the light and screen did get some build-up. I do have massive hair algae growing in the display. I do about 1+ % water change per day via arduino and float switches. I also use the poly bio marine polyfilter organic absorbant sponge thing, easier than GAC and seems gentler... No skimmer, one fish, light feeding, started with dry rock from bulk reef supply. Should I jump the intensity up or just wait it out? Thanks!
