Week old corals bleaching

I've had my corals for a week now. They are starting to look pale.
DKH-6
CAL-over 500
MAG-1140
PH-7.8-8.0
Phosphate-0
Nitrate-0
SG-1.025

Should I only add buffer tomorrow morning? The coals are under Kessil a150w ocean blue lights, they are on for 5 hrs a day. I don't know if it's the lights bleaching them. If so, can I keep the lights off for one day, then do a much slower acclimation to the lights? SPS, LPS & softies in a 90 gal total volume system.

 

It's most likely not the lights. A dKh of 6 would do it, especially if they came from water that was higher. I look at 7 as red light time, and don't let mine go below 8. Raise it slowly 1 dKh per day MAX.

 

Your water chemistry is really off.

What corals are they specifically?

Starting with a slower acclimation does sound in order. Consider placement as well.


Edit: What Jerry said. Bring your magnesium up as well. Moved to-------Corals.

 

Thanks guys!

 

2 acros, 1 montipora, 1 green birds nest, 2 frogspawn, 2 plates, 1 duncan colony and a rock of mushrooms...that are really big and bright still.

 

Well someone made out didn't they. Sweet.

What salt mix are you using?

 

Ha thanks! Funny you ask about the salt. Just now I was like, crap I forgot to say what salt I'm using. It's, Instant Ocean Reef Crystals.

 

Hmmm, seems like you should be higher, unless you have not done a water change in awhile.

 

I do a wc every Saturday morn.

 

Boy your Alk and mag seem low for RC. I am usually around 10-11 alk and 1350 mag easy.
Check you water next time before you add it to the tank.
