acro rtn

have any of you ever had your acros rtn from the tips?.  i am puzzeled why mind are doing that.  all param and temp are where it suppoese to be. have any thought on this?.

i think that the whole light acclimation thing is bs, i took a brain that was under 80 pc for months and put it right at the top of my 90 gal within inches from 2x250 mh, and it thrived 2 weeks later i put in about midway in the tank and it doesnt like it there as much.

ditto Dion, I also have that happening and I have had the corals for 2 months and I started them out on the bottom and now they are about 1/2 way up my rock and it was doing great.  Everything is great I think.  I have done some tests on everything and it all pans out great.  Will they start to die if your alk drops low?  I did have to corret my alk the other day.  It was around 7 or 8 but all the other corals were doing awsome.  Could this be the cause?  Sorry to hijack but I thought you might have something simular

the light bulbs are fairly new (6 month). i have a mess cover over the top to protect the wrasses from jumping out. so too much light, i doubt that would be.  the corals have been in the tank and growing nicely.  two weeks ago some of the corals tips begining to rtn, at that time i also had red slime broke out. i didn't do much about it, and the tank didn't look any better.  so i  went to aquatica and got red slime removal, took care of that and did a 20% water change. did the red slime had to do with the rtn?.  i have not seen more rtn since the water change. but the acro that had rtn look sad. what should i do with the dead  tips?. break it of or leave it. please give addvise. thank you

cl2ysta1, i am running  a calium reactor, alk stay constant at 9.5 and calcium at 420. i didn't mess with either one.

another thing... how are your mag levels?

How many corals are starting to rtn dave?  Is it just one, or is it various? 

I had a really nice millepora coral that did fine for several days in the tank after acclimation in the fuge, and then just randomly started to rtn, and was gone in two days.  Then I have other corals that all but died before the mille did, and are now colored back up and growing.  go figure.

i'm stumped

I've read several things where red slime remover negatively affected SPS big time "after treatment" but you said its improved since then?

Why the cyano outbreak?  Did the temp flux heavy (heater went out), or have you had an influx of nutrients, fish die etc... Generally something goes out of whack for cyano to spread and that may be the cause of the bleaching.  Have you changed carbon recently or started running it?  Generally its going to be one of a couple things, system flux temp/nitrates etc, too much light (new bulbs, or clearer water from running carbon), I'm guessing there are no parasites or nipping fish?

I'd start from there, sometimes SPS is just rather finicky......
