So on xmas eve I was at the LFS which was just the owner and I for about 2 hrs haha. Over his main frag display he has Radion G3's on one side and Hydra 52HD's on the other. Since it was dead we busted out the PAR meter and got to work. He already runs sps AB+ on the Radions and our PAR readings backed up the WWC study at 24" AWL 12" BWL which was about 300 PAR. The profile I made when loaded onto the hydras was fairly close about 300 PAR under the same conditions but the visible color was a bit "whiter" in appearance (It was a very slight difference). Next we dropped the Hydra's to 13" AWL because I have noticed what appeared to be burning on a few of my lower light demand corals (Birdsnest in particular). What we found is when dropping to this height par jumped to nearly 400 at 12" depth. After messing with the settings for a good bit we settled on reducing white, red, green by about 30% and came up with a 12" AWL profile that I am now currently running on my tank. He is keeping the original profile running on his tank as am I the new on mine so I will update in a month or so with our results.I will say however that judging by the PAR readings we gathered and the visual spectral comparison observed between the radions and hydras I would put money on the fact that we will see similar results to the radions running sps AB+. Attached are the new links to both profiles. Happy reefing!!!!! AI SPS AB+ 12" AWL ( https://1drv.ms/u/s!Akco_cmvvLNrgZhvyvRF4Kf5orQL7w ).
