coral dying

is this Dinos or diatoms? It smothers my corals and comes back everyday.

Hey all, I recently ordered some corals from Top Shelf, as well as a leather coral from a LFS & I'm not having very good luck with them. I had some zooanthids in the tank prior that are all doing great, as well as a star polyp that's doing good. Once I acclimated the corals & settled them...

Hey everyone I really need some advice lowering extremely high phosphates. Here’s a bit of a backstory (sorry for the long read) My new build is relatively new just a few months. It’s a 125 gallon AIO DIY system , the rock work was recycled from my old 75 gal but it was bleached and then...

What is killing my frags? It is hard like barnacles. I dipped the corals in Revive and tried peroxide. I did water change, but these white dots keep multiplying and my mixed reef is dying. Is this barnacles? I don't know what to do. It is in my 100g tanks with fish and invertebrates. I have both...

Hey guys, I’ve been dealing with a Dino outbreak in my tank and to answer some questions coming my phosphate is at 0.2 ppm and nitrate at 36 ppm. Last few days I’ve been siphoning out as much as possible I just dosed virbrant (1ml per 10 gal once a week). I’m wondering if I can dose vibrant and...

Hello, Two days ago I saw that my purple-metallic montipora colony started losing tissue. Yesterday my colony was dead. Tissue was turning into brown jelly at night and at the morning skeleton was white. Day before montipora started daying, I lost Acropora frag which i decided to move after...

Hi! First, can someone tell me the name of this coral? Someone bought it for me and I’m not exactly sure what it is. Secondly, it seemed to be doing good when I first put it in my tank, but now it looks like it is dying off. I have a 100 gallon tank and it is in the sand at the bottom. It...

Hello, my coral lost tissue in very strange way - about half of each polyp lost tissue. I don't know what could be the reason. I got this coral about 5 days ago and it looked very well. I have very good parameters.I keep sucesfully corals such as acropora, fungia, micromussa, euphyllia, chalice...

My GSP got covered in hair algae but was still opening just fine. One day i decided to brush it off and ended up hurting it a bit. It began to open less until this point where i believe it’s dead. Is there a way to revive it or is it long gone?

Hi everyone, This drama has been going on for quite some time now, so I will try and cut straight to the important bits. I have a 130L tank, that's being on for over an year now, and I've been battling GHA since the beginning (which was carried over my previous tank, that's on me *facepalm*)...

I have this blasto directly under my powerhead which it was puffy for a while. I then saw it this evening to look like this. Is it dying? Anything i can do to save it?

Hello everyone, this morning I woke up to a strange white skeleton in my tank and when I got closer I saw that it was my green and purple frogspawn. It has been in my tank for 5 months with low light to aclamate it to my tank. It was doing really well these past weeks but this morning it just...

I’ve had a branching hammer coral for around 9 months and it’s been doing really well. Earlier today it was fully extended and happy. This evening I’ve looked and it is very shrunken and looks like a brown ballon coming from its mouth. Never seen it do this before. what could this be?

I had a pulsing Xenia come in the mail yesterday from a frag pack. All but a couple polyps have fallen off and they are stringy looking. Could I save it if so how ? Will post a pic later. (Btw I did do all the acclimation steps).

This is the current state of one side of my poor trachy. I got him about 2 weeks ago and on the day after successfully acclimating, inflated like a balloon, ever since though he's been pretty tight to his skeleton, and now it's gotten so bad I think I can see skeleton and I'm seeking help. I've...

Hello! I recently purchased a montipora capricornis online and it has undertaken some serious damage. At first I thought it was bleaching but I don’t think that’s the case as the other corals I have, including 2 other montis of different species, are doing just fine. Perhaps something is eating...

So no matter what I do most of my corals are slowly dying all except my 2 hammer corals, it’s my softies like clove polyps and purple anthelia that are dying first my purple anthelia was the first to go and the rest are still hanging on, my tank parameters are, ammonia 0, nitrates 5-10 , ph 8.2...

Hi all, I recently had an outbreak of brownish reddish stringy algae in a year old, 30 gallon tank. (which I think was dinos) I dosed Vibrant as per instructions and now my alveopora/zoas/ric are closed up and seem to be dying. Monti's seem to be fine however. I did a lot of manual removal of...

Need help ID this growth and how to get rid of it. It’s very slow growing. A dark brownish green color. Won’t scrape off. I used vibrant for green bubble algae and it didn’t slow this growth. 2 photos are from 2 different sides with blues on and aquarium cam auto settings. Last is with just...

Hi there This does not look good!! What happened and how do I treat this baby?? Im new to the saltwater hobby and I got this entire tank with corals and fishes for a good deal. It has been 3 months now. Then this happened today. First question, is this a lobo? Or loby? And how do I treat this...

I’ve had this Christmas favia frag for a few months now and he’s been thriving. Lately though I’ve noticed white spot on him should I be concerned?

Alright something clearly isn’t right my Lobophyllia is receding at an alarming rate, others corals don’t show signs of receding or melting, but they did look a bit more pale than usual, my Staghorn coral tends to have a brown tint, which has me thinking if the nitrates and phosphate play a role...
