Radion LED help

[MyNameIs]

I have 2 radion LED's 10 inches above the water line on a 75 deep blue. All of my corals are pretty much the same level in the tank they are about 8 - 12 inches under the water line. I had them running at 100% for about 10 hours a day kind of like you would do with a metal halide fixture I would run the blue's then let the whites come on and it would turn off the same white would go off, blue would stay on (running reds and greens during this time period as well). Things were pretty brown my tank is all SPS. I then bumped it up to the same cycle just up to 14 hours. Things started to color up really nicely at this point however it seems to have gone a little to far ended up bleaching out part of my ORA pink lemonade, birds of paradise is starting to look a little to white, forest fire hates me at the moment. I have lowered the intensity to 80% still at 14 hours hoping that will work. I am just trying to get a feeler from anyone else on the forum who is strictly SPS with Radion LED's and as to how long your photo period runs.

ALK : 8.6
Calcium : 450
Magnesium : 1200

I have 2 as well. They are hard to find the sweet spot on spectrum and intensity. My corals started to brown out at first. Then they started to bleach.. My problem is i had them set to low in intensity.. I started at 35% and moved up every week or so till I hit 50%. But still had browning and Bleaching and my red planet RTN'ed.. You want to acclimate your corals to the new light (even though I did and still have issues).. So after the graph that i custom made wasn't working out so well I just went to the 20K preset(in artificial mode) and bumped up the intensity a bit maxing out at 55% now. I tried to go up to 60% last week but noticed my orange digi started to bleach faster.. So i set it to 55% yesterday to see what happens.. My original lighting was 2 X 250 MH lighting and some reefbrite LED's. I have read that people coming from simmilar lighting as my original did what you did and went 100% right off the bat and everything was fine. Then I read people doing that were having issues of RTN and bleaching.. These things are tricky. I have also read some people with SPS tanks max out there Radions at 65-75% with good results. If i were you I would probably take the intensity down a bit

I knocked the lighting down to 55%, which is a pretty big drop so hopefully it doesnt affect my corals in any bad way. Its super weird to because while some corals like I stated are bleaching or browning....my red dragon just keeps growing in the spot its in and its the only coral in my tank besides my Acans that are doing great which is really weird because you always hear people complain about LED's and Acans. How long do your lights run?
