What type of Radion and how many ?
@ milto29 : i've just 1 radion G3 Pro without wide angle lenses.
It's currently 13 inches above the surface of the water.
i use graph of Cakeman and I wonder what this graph was given elaborated 'cause I find that the rate of red LED is too present and scientific studies have shown that too much red was bad for corals
I'll post letter on when I get home my graph. It's the High Growth graph. I just modified it to my liking. I'm still in trial and error with my Radion. As I only have had for about 2 weeks now. I do see that all of my corals are opening very nice. Zoas are multiplying , Green Bubble Coral is looking like a ballon , Green Star Polyps are spreading and my Red Mushrooms are doing excellent. I have noticed a Very Big difference comparing my old cheap LED lights to 1 Radion and a good difference. I just want to get the Radion perfect for my tank.
