coral death

My 16 gallon reef has been stable for the longest time, until I got bubble algae and started to increased my water changes which got to a point where my nutrients were too low and now I have dinos. I had dinos about three weeks before I decided to do a blackout and all of my coral was fine, but...

Hi all! For the past 2 weeks it seems like my tank is going downhill and I don't really have an explanation for it. A bunch of my torches are receeding/dead. My Scoly seems to be super shrunken into its skeleton. We have had a bunch of montis die after they seemed like they were doing fine. It...

We just got back from 10 days away to find this weird, thick white substance in our sump (pics below). It's pure white, thick and is mostly on the display drain tube, and on the bottom of the refugium. There is some in the crevices of the live rock that in the refugium too. It blows off in...

So I have had a small bubble coral colony in my 32 gallon biocube since december. It was doing well in the tank until the past month or so I started to notice a drastic regression in health. In the past few days I think it has officially died and I am at a complete loss. I made no major changes...

So as you can see in the pictures provided I have recently started to lose most if not all of my lps coral, specifically torches and hammers. No matter where I put them in the tank in the span of a couple days or weeks they all seem to shrivel up and melt away. Some of the hammers and torches...

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?

Hello all! I have been quite inactive for the past year but I am coming back. My tank has undergone a lot, right now I only have a clownfish and a pajama cardinal in the tank and just did a massive rock cleaning trying to remove as much bubble algae. Tons of corals have died. It might have been...

Long story short: A move was supposed to take 2 days with a third day dedicated just to moving the tank. None of that happened. Move ended up lasting almost a week with no time left for the tank. Electric got shut off earlier than expect at the previous house. No way to make saltwater for 3...

I recently lost another Stylophora frag and birdsnest frag. These are the second one of each. Both times, they’ve started turning white and dying off. I’m not sure what’s going on since my montipora digis and Pavona are doing amazing. I had both of the frags at the top of the tank (same place...

My coral has been doing really bad as of lately. Some have bleached and others have died. As for the past year I haven’t had many fish only 1 clown in a 60 gallon. The nitrates have been at 0 for the pst couple months and everything else seems pretty normal. I haven’t changed my lighting in a...

I have had this coral for a few weeks but it is looking awfully pale, I want to know if this in dying or not. I target feed all my other corals and they are growing slowly but still alive. I just moved this one from the top of my rocks to the sand bed as well today.

We got some new corals in 3 days ago and we’re now having some issues. Yesterday morning one of the new corals was half covered in a white stringy web-looking thing that was kind of flapping in the flow. I blew it off, only to find the coral below was bleached in that spot. Very back middle...

I cannot seem to figure out why my corals are dying, iv checked loads of my parameters and nothing seems to be pointing to a problem. Any ideas of possible reasons for the death. Thanks. Parameters: Salinity: 1.024 Dkh: 7.5 Temp: 25.6 Nitrate: 10 Nitrite and ammonia: 0 Calcium: 360ppm...

Hey everyone, I woke up this morning to my hammer coral losing its polyps, and looking like it was half eaten. I've had it for about a month and everything was fine until this morning. My other corals appear to be good. Ammonia 0.2, nitrite 0.02, nitrate 2, salinity 34, phosphate 0.04, alk...

I just got these kryptonite candy canes a few days ago. They split between the pollops after bringing them home and now the tissue is receding. I’ve moved them higher in the tank where the flow is less and they’re about 8” directly below my light to get some good light. What can I do to help...

So in the last two weeks my tank has gone from great to bad my female mandarin starved (out competed by male) my acropora colony bleached / turned almost completely white I'm not sure why my stylophora frag bleached / turned almost completely white I'm not sure why my torch coral has lost...
