wow that was fast (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...

Sorry to hear Mark.

Not sure if I understood what you meant about Zeo? If you meant that it didn't do a whole lot to prevent RTN then I would agree, I tried in vain to use Zeo as a mechanism to prevent inexplicable SPS losses but it did not make a difference. Water looked fantastically clear and PO4 and NO3 were completely zero, but coral losses were exactly the same before and after.

Unfortunately this is the nature of SPS. Sometimes they just kick off for no apparent reason. Hope that it's just the one colony for you and not a 4 year nightmare like what I've had to deal with (I wouldn't wish what I've been through on anyone!!)

my comment re: Zeo was in response to Skimmin's suggestion.

I'm not using Zeo or other and unsure if it would make a difference anyways and your experience seems to imply such.
