I'm living the ai LEDs perfect for my setup I'm still only running them at 40 percent white 46 on each blue and I have seen increased growth on my coral I'm running them 16" off the water
Very minimal shadowing the only shadows I notice is at the very top under my flow accelerators but the corals are pretty much right under them do I am completely happy. I highly recommend them. The tanks just over 6'x30 I believe
