SPS help!!!

[Tokyoyankee]

This morning, I noticed that at the base of an SPS coral is white and it looks likes almost peeling. Please and advice on what it could be would be greatly appreciated.

from pic your rock seems to have a algae problem, have you had a cyano out break recently. maybe some cyano covered up that section, also has any other coral touched that area that bleaching, flessh seems to be slothing off. whats your alk and cal at and other levels

Looks like RTL ( rapid tissue loss) they arenotsure what causes it bit it is often caused by a rapid drop or spike in alkalinity. I would check your alk asap, sometimes if you remove the affected coral and cut off the dead part and dip the remainder you can save it. It has happened to me a couple of times, one time was due to alk drop the other I never figured out what caused it.

I just check my ALk, 206ppm. This is normal for my tank. Last week, my lights went out and it took a week for the replacement circuit boards to arrive. Very strange! The other corals look fine. It's progressing very very quickly and is almost half way up the colony. I decided to frag it into 4 pieces. I hope the frags can survive. Thanks for the heads up!

See if it has no basis in each redbugs eggs, is a worm that eats coral tissue, it is better if you give him a bath to kill coralRX of this plague, otherwise can infect all your SPS, grab a magnifying glass and give a look at it, these are redbugs brown are flatworms of sps and quickly end up with all of your tank.

Check to see if there's any AEFW.

have you done a large algae removal lately ? or change po4 remover ?
usually occurs in case of po4 reducing too rapidly.
of course make sure your CA++ is inline as well.

Actually, there has been an increase in PO4. Just checked with my hanna checker. Its currently at 0.19ppm

the high po4 is not good for the coral it will brown out the pigments in the sps. Algie can also cause the coral to start to stn. If u have algie on the coral or has taken root then your best thing to do is cut off the dead area of the sps and then dip in coral rx or revive to kill the algie on the sps.
