This is typical of a low nutrient tank syndrome, if you add a few more fish and up the feedings there will be more food for the corals, IMO if you have changed the bulbs recently then the par on the new bulbs are too strong, for the time being I would keep up with waterchanges, feed more add more fish and perhaps only run the 2 blue plus and leave the rest off. Running all your lights will bleached the corals and basically nuke the bleached corals further. Do you get any sunlight or daylight in your home? If so that will help abit. Looking forward to some pics to see what state the corals are in.

I bet you need to add nutrients. I use pohls xtra special and zeofood7 for nitrate and phos. I have a very small bioload in my tanks and need to add nutrients for my corals.

I'm trying to upload pics but its not working for what ever reason

Here are some pics, I don't know how to get the camera not to take them so blue, the corals look better in person

My thought, just add more food and raise your light up a little, maybe 6inch.
When I ran ULNS, I dosed KZ Coral Vitalizer, Amino, and Xtra.
The easiest way and cheapest is just to add more fish, and feed your fish.

Or you can just dose NO3. All you need is a trace amount in the tank.

i went to JL today to add more fish, but I'm not sure what to add... i would like anthis, and a few wrasses, any ideas out there?

Maybe wait on adding more fish until you figure out what is going on with the coral? I know that is probably not something you want to hear, but it is the best thing for your wallet, the fish and and your emotional health.

Corals look ok to me, abit pale but not that bad.. if you add anthias be prepared to feed a bunch of food. A wrasse would be a nice addition, the tonozukai at Jl is pretty cool looking, I bought the larger one awhile ago. Now that you've stopped po4 removal if you add a couple fish and slowly increase the feeding by summer corals should look awesome. I am not sure why when you said corals I thought your Lps was pale. Sps is not a problem, just takes abit of time to colour up.

Doesn't seem like you have any fish in your tank atm.
Personally, some wrasses that will help combat pests and tang for algae (although this isn't your issue). I also like blue green chromis.

Yes I deffently wanted to add a few wrasses but slowly very cautious of doing things too fast, that's one thing I learned with all the mistakes I made
