wow that was fast (RTN?)

The flesh is just sloughing off and looked fine last night and can't say I noticed an problems afternoon.

Problems started a few of months ago when had one type of Xenia started to shrink but everything else okay. Then a couple of months ago some die off on a single SPS colony but it's be holding on since I put this thread up, and now the Milli today.

Sort of sucks.

Wow! Sorry to hear that Mark. I'm wondering if there is some underlying parameter issue. I know you use R/O... Hmmm. What about trying ultralith or zeovit? I know it's not a solution to all problems but my understanding is that it 'scrubs' your water and then you add back in what you 'need' based on what you have for corals.

RTN sucks man, sorry to hear.
Might be to late now, but you may be able to save it if you crazy glue the edge of the living and dead tissue.

Do you use some kind of buffer?
Such a fast bleaching and detachment of the tissue"

Is usually caused by a sharp change in alk.

Well just tested the usual and nothing seems out of line. Not manually dosing anything as use a reactor and it's behaving (not spiking alk). Alk 10.2 dKH, Ca 410ppm, NO3 usually zero but now 0.2 but then did just loose a large colony.

Zeo or other, not sure if worth trying as thought people used more to get the colours than prevent RTN.

That sucks, sorry you lost your coral

What the hell?
I can't believe how many posts there have been lately on RTN. All posters state that water parameters are fine and that there is no apparent reason for the losses. If I remember correctly, last summer there also seemed to be more coral deaths than usual. I wonder if the warmer temperatures are causing more problems than we are aware of. Maybe not so much how warm the tank gets but how fast the temperature rises. I've seen quite a few posts where the member has stated that his/her tank temp rises considerably from morning to afternooon. eg: 78 to 84 in 5 or 6 hours. That is a pretty substantial increase in a short period. Maybe I'm way off base here but something is definitely going on.
Mark. Sorry for your loss.

I haven't run a temperature plot off my controller (will this afternoon) but between central air and the controller, controlling a heater and evap fans I'm fairly steady.

Read about crashes after a few years (old tank syndromes?) and DSB suspected but I'm BB.

This keeps up I'll have room for a Fish Only tank (trying to think positive)

Yea agreed. That really sucks Mark. As Lance said, what the heck is going on with out sps colonies? Sure makes one scratch their head and sometimes wonder why we never stuck with nice wavy softies.

Agree with you there. Shortly after I first set this tank up, it was overrun with Xenia swaying from the 4way thinking why do people do SPS. Guess the SPS are like crack, get that taste...
