acro STN questions

by **JamieZhu** on 08 Apr 2016 19:02

I have been dealing with STN to one of my blue acro for 3 month.
I got this acro shipped to me 3 month ago, due to bad packing half of it is bleached right after bag opened.
I managed to save the rest of it in a month, later i had cut all remains and mounted on a new base.
After that I noticed STN on its root and top part is growing, then I cut it again on the bottom part as its usual way ppl deal with that kinda of problem.
Guess what that shit happens again, all tips are growing and bottom fucked again.
I just done its third cutting, I cut way up from its flesh and I dnt understand this at all,
I dnt think its kinda of infection or disease some sort ... anyone has better ideas?

Hi Jamie,
That could be a reason of light if strong not enough -shadows.
Also can be a reason the bad quality of Frag plug, glue, parazits.

i thought about that at beginning, i moved at different spots but still the same.
i was using glue to seal bleaching part to prevent it getting worse but no help.
the funny thing is that top part grow faster then the bottom bleaching part, it still become bigger after all.

It happend to me a few months ago with a Simplex I managed to save two pieces it's very hard to tell what can cause 1 coral in the tank to stn

i remember ppl use iodine dip after a fresh cut sps frag, maybe that was a way to prevent infection, but would that be the case happened to me twice ...

what was the method you use to save those two pieces?

it really confuse me at this stage.
the way I judge a healthy coral is by look at its growth, but this one is growing and dying at same time ... like the skin moving from bottom to top, and the stn happens very very slowly ...

I put them in a lump of epoxy and left them on the sand bed I had about 6 pieces only two stopped stn

Adding coral snow will help as well

KZ Coral snow is Calcium carbonate. How can the Coral snow help to stop of stn?
What is treatment in there?

It binds harmful substances together so they can be skimmed out and it is beneficial for sps corals
Water is much more clear after a few hours so better par for Corals

I also have a similar problem on a yellow/green acro which I've had for nearly 2 years, about 8 months ago it started stn in a patch from bottom up until it just stopped and made a full recovery, it started doing this again approx 2 months ago and once again it appears to have slowed down, nothing in my most recent ICP test, ill be sending another one off the end of the week. I didn't attempt to frag it. Not much use to you Jaime but I'll let you know how I get on. All other corals doing excellent and like yours this particular one is also showing excellent growth.

I have had the opposite. Coral basing down;encrusting rock but the tips has TN. Usually there's always something off like alk levels the main culprit. But most cases by the time I see the TN it's already too late to save the coral as the cause was already few weeks old but reaction only later. Tried dipping and glueing but coral inevitably dies off. Talking bout small frags. Larger colonies can still recover of course when cause is rectified.

Sorry, do you know what is Calcium carbonate?
Is not an absorber, very bad absorption rate has a Calcium carbonate. You can ask about that any one who knows a chemistry basis.

Also , after snow usage clear water is only optical illusion, unfortunately.
