What are your tank parameters? Light, gallon size etc?

Ditto -

Although - it looks like a lighting issue - more info about your tank will be very helpful

i got a 65g with a 55g sump 25w uv sterilizer,protein skimmer,an outer 342 watt outer orbit metal halide,light,2 koralia 2,and a maxijet 1200, with a wave master pro.i havent cheked my water in a while now,i assume its good.since my other corals and fish look good

that's what i thought too then i checked my water & to my surprise my nitrate was way high so please check it

 

[Killerdrgn]

you know what they say about assuming....
You need to test phosphate, ammonia, nitrite, nitrate, calcium, alk, ph.
And an educated guess from you adding the sand would be that you caused another cycle in your tank by adding 3" of sand, and killing off all the aerobic bacteria.

i think it might have been the new sand u added? might be an ammonia spike? im not sure

It wouldn't hurt to check your tanks temperature either.

my nitrate is 20 is this to high my ammonia o ,nitrite 0,oh 8.2 should i do a water change?

 

[juiceguy]

when adding sand to an established tank, it shouldn't be poured right over the existing sand bed but mixed in with the existing sand. my guess is you disturbed the balance in your tank

 

[KathyC]

Nitrates at 20 isn't awful, though they could be lower.
When did you switch tanks?

an outer 342 watt outer orbit metal halide

Could you re-explain your lighting? Was this a a recent upgrade?
The rics look bleached...

a changed tanks like 3 months ago, i went thru all the algae,bubble,brown,and red,now everything is ok except for this corals.im clueless could low calcium be the problem?
