my 90 gallon reef tank

[yellowtang03]

I wanted to post some pics of my 90 gallon tank setup with sump also. Currently just starting to add corals but having some bad luck with my lighting I think. Tank info is Marineland cornerflow 90 gallon, 30 gallon sump, reef octopus classic 150 skimmer, panworld 100px-x external return pump, and ecotech gen 3 radion lights. I upgraded from a 75 gallon to this and in doing so switched from t5 lights to the radions. Every since then seems like I

cant keep corals alive. I have lost quite a few due to this now. I have tried to turn the intensity down and slowly raise it...so do you guys think the ATI sunpower t5 bulb is a good fixture? I am thinking about switching to it. Always had good luck with t5. Here are some pics of the tank now. Thanks for any input.

Nice looking, how long has it been set up? Whats your mag and calc levels?

Tank has been up a couple years and all levels are dead on. Didn't have issues until I switched to led lights...seems like they either bleach corals or no growth...can't find a good point and setting for them.

What levels are you running your Radions at? They are much stronger than they appear. I have two Gen 3 Pros over a 105 mixed reef that max out at about 60-65 % with the reds, greens, and whites never making it past 15% (with royal blues and blues at 100% and UV at about 50%). The white lighting on your pics looks extremely high...which will bleach coral pretty easily.

Overall intensity is set at 35% right now and I have it on acclamation mode curently for a 6 week period. I am also running cakemans graph that he posted on here a while back. Hoping turning them down on acclamation mode will help. I have 2 gen 3 radion but they are not the pro's.

Can anyone maybe send me a graph schedule you use for the radions that has worked well for u?
