stn

So I’ve been having trouble with sps having STN after about a week or two. I just received my test relays back and would love to see what people think would cause this. My alk, calc, mg are all super stable and alk fluctuates 8.7-8.5 daily.

Hi Everyone, just got my test results in for the ICP. Need your help identifying what is out of whack in my tank so I can get it fixed. Looks like I should dose some trace elements? Aluminum at 41.26? dealing with STN for a while on Acro, so would be great to nail it down

Hi everyone, need some help to ID what's going on here. Lost a few Acro to this. Seems to be STN? Does the decay pattern suggest pest? I have not seen amy red bugs or AEFW, just have some pods crawling on it lol. NITRATE - 2 Phosphate - reading zero, but pretty sure their a bit ALK - 8.6...

Hi, I am starting to get into SPS and I just bought a frag from a local fish store. I just noticed white at the bottom and I am not sure what it is. I was hoping y’all could educate me. Thanks!

As you can see the JF Kamikazi on the bottom left is RTNing pretty fast noticed it about 3 days ago. I am going to cut it up. However, last night I noticed the monti was getting the white fuzzy almost fuzzy like spots. Is this also dying or is something eating it? I have been observing them for...

I made the rookie mistake of calibrating my refractometer using RODI, checked against LFS water to confirm no egregious slope errors. Refractometer is the red sea unit. I've been reading up on it and seeing that it's incredibly finicky and prone to giving vastly different readings on the same...

Weve got four chalices in a mixed reef where everything else is doing okay to well. My acros are all starting to encrust, and we (meaning she) figured out where to place favias, lobos, favites, and a trachy without melting them. These freaking chalices are all receding, though, and have been...

As said in the title, four corals are looking rough out of 18 total. A favia and favites, and a monti and acro. The favia and the monti were placed too high, and turkey basted a little heavily while dealing with a brown algae bloom. Didnt look like cyano, I'm thinking it was diatoms or...

Hello!! I would like share some pictures about my corals that are dying and my parameters in order to get feedback about it and if you have recommendations to save it. I stat to see this condition since 2 weeks ago. things that i changed 1.-increase the light because i was only used blue light...

Hi, I've noticed the underside of my birdsnest bleaching out. Is this simply due to a potential lack of light or maybe something else? If it's STN then I guess I can refrag as needed, but what about lack of light? Is this just an inevitability as corals grow out? Params are generally stable as...

My tank has been on a downward spiral for about three weeks. I posted in a few FB forums and the answers I received were related to the possibility of current in the tank from failing pump/heater, or magnets leaching aluminum. I wasn’t able to identify either of these issues in my tank. Tank...

Alright, where to to begin. I have had a 80 gallon with a 30 gallon sump tank running for almost a year and a half after a restart. I got dry rock and dry sand, which is a mistake on my part, and I am on a fun roller coaster right now. Around 5 months into my restart things were going okay...

So lately I have been having an issue with STN/Tip burns, anyone have any suggestions? The highest my alk has ever been is 8.8. After seeing the tip burns I dropped it over the course of a week to 7.5 and have maintained that ever since (I have a Trident). I dose 20ml of Acropower every 3 days...

It hits some corals and others look like they love life. Tank is 2 years old. Over the past two months I had made changed to lights, replaced GFO, and removed one of two overflows. I run a skimmer, GFO, Cheato with a bright light, calcium reactor, 450 par on the top shelf and 100 on the floor...

There is a lot of talk about curing Rapid Tissue Necrosis (RTN) and Slow Tissue Necrosis (STN)Lately. How do people deal with it? In the comment section - please post how successful the treatment was - and why you used your particular method. Though it might have been better to allow people...

So if you haven't heard...Prime Coral has some impressive videos showing a parasite that's responsible for RTN and others that might be responsible for STN. This guy is from Florida and his name is Dr. Ara Deukmedjian. This Philaster parasite that he's captured on video eating acros sure fits...

Please...anybody with a microscope...join our battle in finding out all Parasites/Protozoa responsible. See thread below: See page 57 https://www.reef2reef.com/threads/andre’s-full-blown-300gallon-sps-reeftank-up-within-a-week.339591/page-57#post-5763513

Ive had this rainbow montipora for a little over 2 mos. As you can see its almost covered the whole plug. However, in last 3 days this has shown up. Ive searched for nudis and not found any. This is my only montipora so i dont have reference. Other corals are doing better than ever. Even a favia...

Hello everyone, I started my 60 gallon shallow reef tank last Aug 2018 and all is doing fine until the other day. I noticed my birdsnest "in the middle top of the picture" is starting to have tissue loss. It might be STN. tissue loss is on the top side of the BN so i know its not phosphate...

So I've got a 1 year old system. 150 gallon total system volume. The lights were all measured out with an Apoge PAR meter. Nutrients are all in check and all of my SPS, LPS, and Softies are growing like crazy. To clarify I've several acorporas, a pocilapora, and a stylophora that are all...

I came to work only to see this. One of my nicest pieces is STN in the middle. Do you guys have any idea what it could be? Salinity: 35 Alk: 8.6 Calcium: 440 Nitrates: 10

I too have been struggling with SPS STN. I have been chasing numbers and trying to attack this from all angles. It keeps coming down to this: If I try to balance the nutrients, I get a hair algae outbreak. Here are my numbers: alk 8.6 CA 390 MAG 1470 PO4 .ZERO NO3 5 SALINITY 1.022 TEMP 78.2...

Hello everyone, My first post. I am fairly new to the hubby. My tank has been up and running for 8 months. I have been wanting to enter the world of SPS. My bird nest have been doing great so I ventured to get one frag of the Blueberry Fields acro. I believe that it is suffering from STN. Any...

I've never had luck with Red Planet frags, but I traded some hammer and acro corals for a large piece of Red Planet and am trying again. I figure a larger colony will have a better chance of survival. Parameters: Ca - 450 Alk - 7.3 Mg - 1290 PO4 -.04 NO3 - 0-5 I've had the red planet about...

Good afternoon all, My SPS have been suffering from STN (all of them), so I performed a Triton Test and have received my results. A quick note; I've been battling GHA for the past few months, and I've almost won the battle (only a little left in the crevices of the rock). My STN started...
