I'm running 2 Hydra 26HDs and love them. I was having some issues with coloration and I read through the EcotechMarine article about their LEDs and recommended settings based on their research in an aquaculture facility. I did the calculations based on converting the Radion LED settings to the Hydra and have been running the AB+ copy for about 3 weeks and I'm starting to see some great coloration from a few corals that never had any color since putting them in my tank. Below are the settings I'm running.
11:30 - 9:30 (1.5 hour ramp time)
UV 118%
V 118%
RY 100%
B 100%
G 36%
DR 36%
CW 24%
