Lighting help

[karla Difiore]

I used to have a 4 bulb fixture that came used when i bought my 75g tank. The fixture broke aswell as the bulbs(didnt work). So i bought a new fixture with only 2 bulbs and a marine land led light. I have a blue plus and coral plus Ati bulbs T5. ive had this light for a few months but my corals are not happy, ive recently tried sps but they seem to all bleach. My bta is not happy as well as acans. But all my hammers seem to be fine. My question is do i have the right light? Should i add another fixture or should i change the combinations of Ati bulbs? Ughh please someone help!!

I ADDED A BEFORE AND AFTER PICTURE..

I'm new to the saltwater scene but from my understanding LEDs can shock coral and bleach them if you don't acclimate them properly maybe the LED is just to intense at first?

The tank looks great. How old is the tank? what are your parameters. This could be the issue of having low nutrients. If your parameter especially your alk is steady then I would suggest raising the light. I have read that members have has better success with combinations of LED and t5s instead of just t5s or LED's. My thought is that the light might be to intense for the top corals. Another question what is your lighting schedule? do you have a ramp up and down or is the light just on off?

I only use the led as a way to not shock my corals i turn my led leave for maybe an hour then turn my t5s on then after 7 hours turn off my t5s and turn my led on leave for an hour then its nighttime. I did slowly acclimate by starting on 4 hours and so on adding more hours

Thanks tank is 2 years. Everything seems to be okay except my phosphates theyre high. At 0.46 am running a reacter to lower them. I lowered the corals to the buttom but no luck its wierd my gps is at the top with no problem. Half my corals are doing great amd half are not i had a torch die a couple days ago.
