coral bleaching

TL;DR: Building an AI system to better detect coral bleaching in the wild. Your tank photos could help save real reefs. Hey R2R, I’m an AI/ML researcher and engineer, and I used to be an active member here years ago before life pulled me in other directions. While I’ve been away from the...

We bought this birdnest coral and it was doing great, open all day, and seemed to be growing. One day we looked into the tank and the birdnest and our montipora was white on one part. At first, it was white all on one side from the top to the bottom, but now it has become white just on the...

Not sure but does this look like bleaching. Phosphate levels are pretty stable.

I just got some corals in the mail from topshelfaquatics. They sent in a sheet saying their flow and lighting preferences too. Both of the corals require medium to high lighting. Anyways, I got a Christmas mirabilis and a birds nest coral, and they seem to have bleached in just 1 day from being...

Hi I just started with these Corals as I was told they would be the easiest. Fish are doing great, levels are great. These pictures are from day 1, but now the ends and edges are turning white and they are not as green. I’m thinking it’s the lighting not being strong enough or it’s the temp I...

I haven’t looked at it under normal light now that I think of it but here are some pictures. Some insight would be appreciated!

Hello, I am a newer reefer, started this year. I am on my second tank already.. I have a 85.3 Waterbox Frag lowboy, it came with two 32 HD Ai Prime lights. I do know how to set up a lighting schedule.... but clearly not one that my corals (soft and lps) desire. My tank parameters have been...

So not sure what it could be, but my torch started losing color and looks to be bleaching on one side. Any ideas? The tank is a JBJ45 running a Hydra 52 about 12" over the tank. I just turned down the intensity on my setting because I feel like my settings might be too high, now peak is now at...

Hi, My tank has a problem with to low nutrients, It`s a triton core 7 setup with a large fuge. I feed 5-6 times a day and dose aminos every day, but still I can’t get to bump my nitrates up. The tank has gradually gotten worse and worse, It`s more or less impossible to get KNO3 in Norway...

I know there are many out there who doubt global warming exist much less what it is doing to the coral reefs and subsequently to this hobby that we all love so much. Its real folks!!!! And it is devastating the reefs world wide. Here are two scientific papers in highly respected scientific...

hey all! Just wanted to post a helpful reminder to check your salinity and calibrate your refractometer! I had during lps corals and bleached sps for the the last week. I tested all parameters Calcium:400 Alk: 9.2 Mag: 1245 Nitrate:5 Phosphate: .12 I couldn’t figure out for the life of me why...

How long does it take for LPS corals regain their color after bleaching?

I've had this montipora for a few months, and it has lost a lot of color since I got the frag from a reef club member. Recently I've seen these snails crawling all over it and don't know what they are! What is killing my monti cap????

Hello everyone! I recently came back from my honeymoon, we were in Mexico and I had the privilege to do some snorkeling in a real live reef! I wanted to share some pictures and video with you all that I took with my gopro! I do have some quick thoughts so here it goes....... I don't consider...

I have a biocube 29, the sump is pretty basic. Chamber 1 hydor slim skim. Opened up the flow into chamber to filter floss, purigen, chemi pure elite, then rock rumble. Chamber three 3 heater and return pump. Two power heads in the back for extra flow in the tank. I have mars-aqua lights on a...

By now you probably have seen or heard of Chasing Coral, a Netflix original documentary that was released worldwide on July 14. The film premiered at the Sundance Film Festival and was acquired by Netflix on the same day. Coral bleaching due to rising ocean temperatures is the focus of the film...
