STN on the base of a huge green slimer

I had the same issue over the summer where my corals got stressed from the tank getting too hot. Then my acros started to STN from the base. I concluded it was some kind of bacteria or that the Coral was starving as my system is ULNS. It was crazy because the slimmer which had a MP40 pointing at it was sTNing and the base still growing at the top. Bringing up my nutrients seems to have solved the issue but I still get STN here and there.

+1 I am have almost the same issue and feeding oyster feast is helping with the same problem you are having. I also have ULNS and since feeding has somewhat did the trick, I also am changing 6 gallons of water weekly now with reef crystals was using Instant ocean.
Hope this helps
Ps I have an mp40 that give it medium to high flow all day.

I would avoid aiming a PH directly at the coral.
Check your Ca and check around the base of the coral for vermatid snail/aiptaisia and anything else that may be irritating.
I know of a fish store which is not to be named, that has bottom up STN. They use IO and I know they have chronic low calcium.

I have been experiencing STN at the base of several branches of my large slimer in the picture below. No other corals show this problem. I have thought it was due to low lighting from shading of the purple rim cap and blue Mille growing next to it as well as reduced flow in those areas. The slimer is actually growing up and out of the caps whorls.
The STN has extended out just past where it receives adequate lighting and seems to have slowed considerably at that point. I monitor it daily to see if it continues to spread. The outer branches still grow at a fast rate. I am trying to avoid breaking it up unless I have to.

Thanks, I am hoping it is a light and flow problem in my case but i worry because it has extended a bit past where i thought it should. It has slowed and i hope stopped at this point so maybe I am in the clear. The rest of the coral continues to sprout new branches, and actually has grown out of the water at a couple of spots. I take frags from it often so hopefully I can just leave well enough alone with it.
Can you post a picture of yours to see what is around it and its growth form? I would like to see if we have a similar situation and maybe we can agree to let them be :thumbsup:

It may just be the pics, but the corals look pretty pastel to me. Some nutrients in the water would likely help the issue. Tank is beautiful anyway!

Thanks, A little of both actually. The corals are lighter than I would like but my picture taking could use lots of help too
I have been increasing my feeding and came to the conclusion my photoperiod was much to long. On my 8 bulb T5 I was running 4 bulbs for 14 hours and all 8 for 8 hours (dummy). I have cut back to 12 hrs total, 6 hrs full lighting, and added an actinic tube. I have seen progress since that pic over the last month already.
I doubt that has contributed to the STN in the slimer though and only paled them overall. The slimer still grows like a weed even with the STN and too long of a photoperiod.

here is a good shot of the STN:

That looks a lot different to what I have going on with my slimer. Mine seems to be a consistent "ring" around the branch that first lightens in color and then the tissue dies off as it moves out. In your picture the necrosis looks to be more patchy and random.
I will see if I can get a good picture of mine later today so you can compare.

I wouldn't say 3 mp40's is much flow in a 300. I have 6 mp 40's and 2 60's in my tank,and it decent flow in my 300 sps tank.

After looking at your picture I would say your tank is nutrient poor.
