I have two AI hydras in a 30x30x24 tank, I don't seem to get to much growth out of my coral. I have had a green slimmer for over a year looks great just no growth, so I'm wondering what people are setting them too?
What is your schedule and intensity settings? I run LEDS and have no problem with SPS growth. It can and is being done.
I had MH and I don't see where the corals under it had significantly better growth or color than the LEDs I use now. Color and growth is about the same.
