Too much possible reasons.Maybe of stress because of moving,transportation etc.If acro is long time in your system and started to lose the colour(but looks healthy without burn tips etc.)it can be because of light.Corals use the colours as a protection against high light,so many professionals says that,if you want them to grow faster-low light,if you want the colours-higher...
Also they can lose the colour because of too much food stuff in the water,low magnium,stroncium or iron etc...

It doesn't necessarily mean the coral is unhealthy unless it is losing tissue.
How do your other sps look, are they Brown too, or just the one single acro?
If all of them are Brown, do a major water change. As others have already said, it could be excessively high nutrients, and a large water will help all around either way.
How old are your lights?
Is your Skimmer running properly?

If water parameters are good then I would say lighting. Bulbs are older or your par has changed. I have found browning is better problem then turning white. Slowly increase light every two weeks till you start seeing color come back. If it starts turning light in color like whitening then lower intensity

First and 2nd pic are of the same coral 1st pic is January 2nd pic is now. 1st pic is when I was experimenting with vodka I no longer use it 3rd pic is of the same coral just zoomed in so you can see more skeleton and polyp extension .......as far as a nitrate number I'm going to invest in salifert kit as my api one cannot be accurate / reliable

Start by checking you water parameters. If everything is normal then move onto light and flow.

A little embarrassed posting these results up...... but I guess that's the learning curve dkh 7.8 calcium 355 mag 1160 nitrate0 phosphate 0 salts at 1.023 (salt will be corrected asap)..... now here's my thing I know I have phosphates in the water as I have green bubble algae patches in my tank I've read before that algae absorbs phosphates so they really wont show on a test let me know if I'm wrong.

Bubble algae can grow in ulns, ask me how I know. I still say that first coral looks starved which would be consistent with your numbers. I'd try adding some amino acids or acropower slowly and see what things look like in a couple of weeks. Your ca is low but that shouldn't affect color.

Your system will get used to the Acropower. I'm putting one capful a day in my tank.

Low mag will make it very hard to get you Alk and Calc levels where they need to be so make sure you raise it to around 1350. As far as PO4 you need just a little bit of it. Bubble algae like Rovster said will grow anywhere. It's a royal PITA if allowed to take hold. So don't go by that with you PO4. After everything is back level and if you have enough corals specifically sps you will have Mag consumption so likely you'd have to dose if WCs can't keep up. Some systems use more some systems use less. I have to dose a fair amount of. Mag I've found out. Glad the coral is doing better.
