Give me a relative size if you can. I.e. how many gallons you system is, to what size scrubber. What it's lit with (total power and colour) and whether it's lit both sides. Does it eliminate the need for phosphate removing chemicals?
That should give me a good idea. I worked it out from 81 us gallon system I needed minimum 8x10" lit both sides with 40w cfl both sides. From what you have here, led power is just under half.
Thanks
