Help with monti/sps corals

[DJNALEN8]

So long story short I have had a tank setup for half a year and added 5 - 6 corals one being a monti, everything is growing good and I get some WWC corals the other day and now everything's bleaching out but I don't know what is causing it!

Everything is located mid tank and the lights are 2 ai primes and a hybrid fixture with t5s and light cycle is AB+

ALK: 9
Calc: 420
MagN: 1400
Phos: 0.01
Nit: 30
Salinity: 35

They don't look very 'bleached' to me. I'd say give it some time. If you didn't do anything but add some corals, things shouldn't have changed enough to cause serious issues.

po4 is low for your no3 to be so high. start there. but as ron mentioned above, give them time to acclimate.

I'll take another photo of my other mystic sunset monti after work and you'll see the bleaching but I'll lower the nitrates and try to aim for 10

After doing a crap ton of reading and light changes I have found monti nudibranch on 2 of them so I quarantined them on Friday and dipped them in revive each and got everything off including eggs, thanks alot for the help peoples! Here's a photo of them now

Here is the cap monti that started it I believe, this is also one of the biggest branch's I have ever seen too! (It was quarantined and died over the weekend)
