dying corals

Hello reefing community, I’m facing an issue where I’m losing my brain corals one by one. In the beginning, I had about 25 brain corals thriving in my 100-gallon reef tank for the first three months. However, I started noticing tissue loss, followed by browning and eventually death. So far...

Hey all, I'm still having issues with the "new" tank. Ever since the old established one popped a leak, ive been having issue after issue. My problem now: algae bloom & dying corals. My star polyps are THRIVING. Everything else? Not so much. I lost a galaxea & a hammer today, al9ng with my...

So i have had this 60litrs nano tank for about 6months now. I have two birds nest coral frag, one funghia, few zoas, ome chalice and one hammer. Fishes only 3. Initially my params were:- Dkh-8-9 Calcium-420 Nitrate- 0 (negligible) Salinity - 30ppm All corals were growing healthy and hammer...

I don’t understand why I am having trouble keeping LPS alive in my tank. The common theme I have is I purchase a new coral and it initially is fine, however, they typically slowly decline over a few weeks and I watch as more and more skeleton become exposed and their flesh starts retracting. I...

Hey guys... I'm really struggling with my corals.. I've kept soft corals for several years without issue (Kenya Tree, Pulsating Xenia, Hammerheads) but I cannot seem to get things right with SPS or LPS corals.. In the photos below, I have two that really not doing well but I don't know what I...

Went on Christmas vacation (8 days had mom feed the fish/dose and watch it we just didn’t tell her about the water level bc we thought ato was not an issue) and when we got home the tank salinity was really high (not sure how high as we don’t have a refractometer just a basic one that goes up to...

Hi everyone, I’ve got a handful of Hammers that have been in my tank for 3+ years and have always done pretty well. Over the past 3 weeks or so, they’ve all closed up (photos 1-3). About 5 weeks ago I added a new coral, I think it’s a Monti(?) - photo 4. I have not changed anything else with...

Hello All, I'm looking for help with health on my 240 gallon system. It's been running for 2 and a half years, and I can't seem to have success with my SPS coral (and now appears one of my torches is dying.) I'm attaching some pictures of some SPS coral that appear to be dying. I think my...

Hello, I have a 100 gallon Innovative Marine EXT100, and I'm losing corals. For lighting, I'm using two AI 32HDs. I run a protein skimmer, refugium (which is not at all growing my chaeto), a Carbon/GFO reactor plumbed into the manifold, and a UV sterilizer. I started this tank in November 2020...

Help! I was out of town for the holidays (~10 days, never again!) and came back to an angry tank. I lost a peppermint shrimp, cleaner shrimp, yellow tang and lawnmower blenny (my first & all time favorite :( ). I brought a water sample to the local aquatic shop and they said everything was fine...

Hey fellow reefers, I have had my tank setup for just about 2 years as fowlr, i have had many issues im dealing with already such as cyano or dynos, aiptasia, slow coraline growth, loosing 90% of fish from ich, dyno toxins, or overall bad water quality. I have since done several large water...

So long story short I have been having some algae issues including red (cyno) and this new hair algae (will include photos). I know my tank is never going to be clean but this is starting to take over some of my frag plugs as well as my rockscape and has started to effect my corals and their...

I was brushing off an acan that is like 50% dead and I didn’t know why it was dying. All 4 other acans look fine. While brushing it off I noticed something shot out of it. Then landed on my rock. It was a worm of some sort so I used a turkey baster to suck it up and put it in one of my test...

Hello I’m very sad this is my first lps coral . I noticed that flat worms was eating my coral and I read that the best is to soak in to ro water for 15sec. Flat worms fall off but my coral looking very bad. I read also It will take time to regeneration but can it be for sure? Please any advice?

Two of my recent addtions to my reef are losing their flesh at an alarming rate. This is a pretty new setup and I recently started dosing BIonic 2part about a 2 weeks ago. Recieved corals at 95degrees Farenheit about 4 days ago. I noticed the tissue loss the next morning. I had been following...

So I thought I would start adding some sps into my tank which has been up for about 2 years. I’ve kept sps in my old 20 gallon with success, but upgraded my tank. I have some montipora, zoanthids and frogspawn that have been doing well. I couldn’t resist a live sale here on R2R so I bought 8...

hello, after cycling i transfered all my corals slowly in a spam of 2 weeks. Now my sunkist bounce once were 3” now looks like its dying or splitting. Anybody knows what this is?? Thanks

I’ve had a reef tank for more than 30 years and have had acros for around 15 years. I’ve never seen this before. Starting about a month ago, several of my large healthy acros started turning white around their bases. Slowly, the white grows until all the coral’s tissue is gone. It started...
