SPS are STN-ning from the base up

i noticed you have a toadstool leather in there. you ever stopped to think that maybe the leather was releasing toxins into the water column and effectively irritating your sps to the point of TN. just a thought, i have heard this from numerous reefers in the past that mixing leathers and sps is not optimal due to the chemical battles that may insue. how is the leather doing? has that been stressed in any way? try to remove the leather for a couple weeks, do some major water changes and see if the symptoms dont subside. just a thought.

You know about the borate issue with SeaChem salt right? Your alkalinity readings will be off with the increased levels of borate in the salt. Do a search for the conversion. I think you simply need to add 1 dKH to your readings but not positive.

How are you confirming that your temp and salinity are correct? I had a new bottle of Pinpoint calibration fluid, which was reading 1.029. That obviously caused some problems.

I also bought a nice thermometer to confirm that my temp probe was correct.

I think with your fish load and good feeding,you may be using to much aminos.This happen to me and once stn starts its hard to stop.I would do some water changes,stop dosing aa,change carbon,gfo.

I'm surprised nobody has mentioned the ROX Carbon. Being that you once vodka dosed, and are probably very close to ULNS, I'd lose this carbon as part of your regimen. ROX is extremely powerful stuff. Your exact symptoms happened in my last tank. I pulled the ROX and the problem subsided. I don't know what it is about ROX and carbon dosing/ULNS, but it seriously strips the water, and is probably best left for those that do small water changes, have feed heavily to a large bioload and have mixed reefs with measurable nutrients. What do you have to lose? If you find this is the problem like I did, your wallet will thank you for it by being able to run a less expensive carbon and changed less often.

Just my .02

I'm going to second the ROX comment. Every time I change my carbon I have some sort of issue. I've had colors fade literally over night, very slow TN at the base of nearly all my acropora, cyano outbreaks, etc. All of my issues seem to crop up right around the time I change my carbon.

As I research the symptoms, carbon dosing seems keeps coming up as a potential culprit. I'm not sure what is happening but ROX either strips trace elements or clears up the water and unintentionally makes my lighting more powerful. Either way, I'm leaning towards getting rid of all my ROX.

I'm using BUlk reef supply rox .08 carbon but previously used kent. Do you think it could be a deficiency in an element like strontium or something else that's not testable? Does anyone feel that dosing Lugols would help the problem?

you said you previously used kent? how long ago was this? all of KENTS carbon was recalled due to wrong usage of carbon. they used AIRED carbon instead of WATERED carbon. something like that. I've read up on it before. and it caused a whole reef tank to crash in acouple hours..

This thread was started back in 09. I don't think Kent carbon is the cuprit....
