stn

So my colony has been losing tissue from the encrusted base for a couple of weeks now. I'm worried I don't know when, or if, I should cut the colony from the base to help save it. Would the encrusting portion not affect the branching portion? I don't want to repeat myself with retyping...

I've had this problem periodically with certain SPS corals. The flesh essentially dies on some of the tips, and sometimes then the entire body gradually dies. Specifically it's been a problem on these Blue Torts. This Tort showed the same effect elsewhere, so I fragged off the good part, and...

I'll preface this by apologizing for the long post, but I'm all out of ideas and my parameters don't tell the story happening in my tank right now, so a lengthy backstory is the only info I have. ICP results are below, but basicly corals started RTN/STN slowly wasting away along with red cyano...

Hey all, Looking for some opinions on the cause of STN in my friend's tank and course of actions. All the montis that are undergoing STN were growing quite well, then started receding for unknown reasons. There have been a few acro pieces that withered away over time as well (some maricultured...

Hello all, I picked up this favia around 3 weeks ago and have noticed tissue reccesion over the last few days. it’s sitting Lower in my tank but direct light and pretty low flow. I know that corals can have a delayed reaction, do you think it could just be shocked from the system change? My...

I’ve been monitoring this mushroom for about a month ive notice the top of it was turning white and I figured it was because it was bumping up against the gsp, even though im not fimilar with gsp having stinging abilities, fast forward to today its now definitely receding, i have another one on...

Hi hive mind! I am farely new to SPS. My tank is 2,5 years old, it is a RedSeaReefer 200XL. It has an skimmer, RedSea90LED and a dosing pump currently dosing only alk. In the tank I have multiple Nero 3s. I have 6 small fish, some inverts, zoas, some lps and a thriving pocillopora and stylphora...

In reefing you sometimes need to act fast! I moved this Miami Orchid SPS coral colony higher on the reef the other day and unfortunately it did not like that move at all! By the morning it was turning white (dying) from the base up. ☠️ I believe it to be RTN (rapid tissue necrosis). As soon...

Hey fellow reefers so I've noticed something strange which is my red Monti Digitata is growing very well on the tips but at the base it is not encrusting at all and in fact the tissue is wearing away a little bit. I'm wondering if this is because of the gel super glue or might something else be...

Sorry for the long post, I just want to give everyone as much info as possible: 3 weeks ago I bought 7 acropora frags, they all seemed healthy and were bought from a local sps guy who is pretty knowledgeable. I dipped them all in coralRX and rinsed them in saltwater before gluing them to the...

Does anyone know what the in tank treatment instructions are for oxolinic acid?

About 2 weeks ago I moved all of my corals from my 20 long to my new 50 gallon system. Parameters were the sam and I adjusted the lights to the same par value the corals were used to in the old system. I had noticed over the past week that my orange monticap has been losing tissue a little bit...

I’m having some really weird stn issues going in in my tank. It’s a 10 gallon and has been going good for a couple weeks i’ve been having some really bad tissue loss on some sps and some lps that i have no idea what it is or what to do to treat. 1.025 sg P04 0.00 (hanna phosphate ULR) NO3 8.0...

Recently, I transitioned a fairly healthy 200g SPS dominant system to a new 340g system. The previous system was stable. Before I broke it down the 200g system, I had started to see some occasional coral mortalities in my frag tank. The new system is 4 months old. Over the 3-4 four weeks...

Hey guys over the last three weeks my encrusting and happy Bill Murray SPS has been suffering from what I can only guess is STN. I’ve had RTN years ago, but this is completely different. It started with the backside becoming white but leaving the tips still colored, if that makes sense. Over...

Hi all. I have a year and a half old system acro dominant system that’s been growing okay not so much thriving. It seems every time I attempt carbon dosing I start getting stn on some acros. This is with one drop (~1/5 recommended dose) of tropic marin bacto balance. This is probably the fifth...

Tips on a lot of my acros have turned white and seem to be spreading down, some have started growing algae on the tips. Could use some ideas and insight. Alk 8.2-8.4 Ph 8.3-8.4 Calc 550 Mag 1400 Nitrates consistently 7-8 Phosphates swing a bit but typically .1-.2 Temp 77.5-78 Par 250-300 (5...

I dont know if this has happened to anyone else. But let me start the story I started dosing my tank with AB+ yesterday, After watching several videos showing how, and talking to several people who have used it, I went out bought some AB+. followed the dosing amount and how to dose to a T and...

So i've had STN come and go and come back again over a six month period. Im like 90% sure it bad bacteria because the only swings I've had was an ALK. drop -0.7 one day and left ATO off another day and Sal. went up to 1.026.5. my tank is full of frags and its only effecting my birdsnest: STN...

So I've been fighting with some burnt tips/STN on my SPS with the following parameters: Alk - 8.1 Calcium - 450 Phosphate - .1 Nitrate - 10 Mag - 1400 I understand that low nutrients of near 0 can cause burnt tips/STN in SPS, but I would have never thought that the levels posted above were...

I have had my tank going for about 1.5 years. Over the last year, I would occasionally introduce an SPS birds nest frag, Montipora Digi or similar "hardy" SPS but so far without success. I have mostly LPS that all do great but any SPS frags, just never seem to make it more than a month. The...

Hello Everyone, I wanted to share my experience with a mixed reef and acropora bleaching / STN. I have been running my Waterbox Reef 70.2 (65 gallon system) for about 9 months at the time of writing this post and I have lost my fair share of acropora in that time. At first I chalked it up to...

Good afternoon all, I've looked around at all the threads related to this, but it looks like its been some time since the last discussion. Has anyone had any coral loss treating your tank with Fluconazole? If you have used it with success, how long did you use it? Did you have any elevated...

I put several new corals in my 9 month old 65 Gallon tank 2 weeks ago. The softies, LPS, and one SPS (montipora) are doing well, but one acro is losing color and the other acro which arrived brown looks like it is bleaching at the base. Should I apply super glue? I'm worried it's too small to...

A bit over a month ago I got my first Acropora (booberry) frag and it was doing pretty well in my Nuvo 20 for the first three weeks. Though in the past several days, first noticed Oct 7th, this frag started showing spots of skeleton at the tips of the Corallites. The day before I do recall...
