Whats wrong with my coral?

I changed my PhosBan a few days ago but iv been testing ALK and Phos every 12 hours since I changed it. I also lowered the light % when I saw the deep water starting to reseed. It was only 10% total change between the three drivers.

 

I would think so.

 

Thanks, ill check tonight after work.

 

Both of those acros are highly susceptible to AEFW.
I dont see any bite marks but the colors are, IMO, off and there is no PE on either piece. I am comparing both pieces to mine and can see that something is wrong. The suharsonoi especially looks in pretty bad shape. Ill post up a pic of mine to compare when I get home.

 

also check your nitrates... as its uncommon but they can cause this issue.

 

They do have PE, the pic was taken after I moved the coral. The Deep water never really has PE during the day but plenty at night. I did take these pictures with my phone so the color might be a little off.

I forgot to add that, I am sitting at zero nitrates.

 

Also I should mention I lowered the deep water and turned down the lights and it seems to be doing better.

But I'm still having issues with other corals and the bases reseeding.

 

has there been any kind of swings at all? Salinity, alk, ph, calcium?

 

In ALK yes, I was dosing all my ALK at night when the lights were off. I would start at 9.32 at 9am and 8.1 at 9pm. Also there may have been a large swing in Phosphates 23ppb to 10ppb in 15 hours.

But ph, mag, ca all stay within check. Also I just recently had Scott help me program my doser to dose ALK over the entire day but that was only 3 days ago

 

Any swings like this, even dropping your phos can cause issues with some, if not most SPS. I dont have it in me to try them in anything smaller than a 90 gallon tank, just for this reason.
