Very clean setup . Sorry about the struggles you are having . I have been beating the boards on this exact same fixture and can't find a lot of good feedback on them . It's a no brainer that the 8 bulb hybrid units work since the led imho are a supplement . I have also tried to compare the ati model that uses 2 x 75 and 4 x 39 watt .I haven't found any users raving on that unit either . The only difference I see between the two are no white emitter's and the use of UV emitter's . We all know t5's have a considerable amount of UV output . How much hits the corals is unknown but I would suspect its a broad output . Very unlike a UV emitter with a narrow pinpoint light. I agree it's not safe to keep playing with the spectrum constantly . Have you considered using 2 blue plus and 2 KZ NG or 2 Geisemann lagoon blues ? If it were me I would try this and omit the UV channel, and cyan channel with all others 100 % with the red dropped down quite a bit .The intensity would be where you are still at . Again I love your build and have my fingers crossed for you . I hope you find that sweet spot so you can enjoy your reef .
