are these corals dying?

[d_icemand]

some pics. They have been through a lot with a tank swap over from 65 to a 120. so I know flow throughout the tank is different. Also a different type of t5 hood with new bulbs (same combination as before only 4 foot long)

yes sad to say check the alk it looks like an alk change and the tissue has burnt off.

Does look like some STN....

STN????? whats the abreviation?

[goochesfish]

what is STN?

 

[blu_devl_06]

Slow Tissue Necrosis...slow death of SPS, where the dissue is dying, could be a number of factors, temp swing, trate spike, salinity swing, stray voltage, putting them in the sandbed, lots of things can **** off SPS....

What should I do? the tips are still alive---do I frag them off or leave the coral alone?

 

[myaerica]

frag them before they to die off.

I am having the same issue! Some of my colonies are 3-4 years old and tissue is just disappearing. My LPS are doing great but I am seeing signs in all of my Acros. The tips turn brown, or they get stringy and then tissue starts disappearing.

Can anything be done to reverse this? I have a huge tort colony that I don't want to lose!

Thanks

We all go through it at one point in time- mines also going through it- only way to stop it is to prevent it. Everything that goes into your tank test . new saltwater test it from the old batch. Make sure your magnesium is high so your parameters dont shift. My salt change made my alk go up and then a sea shell got stuck in my reactor causing my alk to go from 9 to 13 down to 8- complete loss on half my corals - best thing you can do is stabilize them hope for the best and cut what looks healthy with polpys . also make sure you cut above a few millimeters of healthy tissues so you ont get any weak tissue. Its the problems that make you stronger and smarter- alnd also gives you more room for more coral

thanks for all the advice.

Its gonna stink to cut the big coral down to little frags and start all over.

I just hope the frags make it. I lost a Millepora colony that was 10" across!
