sps bleaching

I have several large SPS Colonies that died recently and have tried to figure out how to remove the dead skeletons. They are hard as the rock. Literally. I can cut some branching but the majority is encrusted. I have several colonys that are alive and recovering but my tank looks terrible with...

Hi all sorry for the long post, I have a Cade 1500 S2 that I purchased second-hand from fakebook around a year ago to upgrade from a Waterbox 90.1. For the first 9 or so months I have had no issues with the tank, and transferred the majority of my live coral and corals across to the larger...

Within the last month, my monti cap bleached randomly and seems to be spreading to the leptoseris (which had been touching the monti cap). Any idea what this is and what to do about it? Been monitoring the last couple weeks and seems to be spreading. I suspect that it may have been higher...

Hi All, On one side of my aquarium, my Monti's, Acros are just bleaching overnight. Parameters have been stable for years, Triton tests are perfect and nothing has really changed in terms of flow and lighting. It started off with one Monti, a couple of weeks ago, Now more corals are dying in...

I bought some corals during the TSA live sale. I got some zoas, clove polyps, a hammer some favia, montipora, and a chalice. I was able to get 2 $1 acros and a free acro. So I figured I’d have a go at it being that worst case I lose $2. I saw online it’s better to let the corals sit in the frag...

Help! I’ve been having issues with SPS for months now. Every SPS I introduce to the tank develops RTN within 48 hours. All of my LPS corals are doing fine. Even this coral has good polyp extension when in the water. I have not seen any pests on them, but i could just be overlooking. I added this...

Hoping for some more eyes on this to help me nail down what's wrong with my green goddess birdsnest. She was doing great for months after a rocky start in Nov where it lost over 90% of it's polyps after accidental exposure to RO water during the initial introduction to the tank. (noob move on...

So last night I changed the media in my GFO/Carbon reactor. I have run the reactor for 6 weeks or so. My phosphates were at .17. After adding new media last night, they plummeted to .04. Within hours, my 2 previously happy SPS pieces looked bleached. The monti at least now has its polyps...

Hi! Recently out of the blue my SPS corals are turning white, and some of them have a reddish-brown color. Not sure what is causing issues, some stats are: Temperature: 79.3 F NO3: 13-12 pH: 8.2 PO4: 0.07

About 2 weeks ago I moved all of my corals from my 20 long to my new 50 gallon system. Parameters were the sam and I adjusted the lights to the same par value the corals were used to in the old system. I had noticed over the past week that my orange monticap has been losing tissue a little bit...

Tips on a lot of my acros have turned white and seem to be spreading down, some have started growing algae on the tips. Could use some ideas and insight. Alk 8.2-8.4 Ph 8.3-8.4 Calc 550 Mag 1400 Nitrates consistently 7-8 Phosphates swing a bit but typically .1-.2 Temp 77.5-78 Par 250-300 (5...

This was my first coral and has grown from about 1.5 in to the size of a strong fist in the last 10 months. It has always been the happiest and most aggressively growing coral in my tank and in the last 2 weeks it's DYING!!! :'( Here's what it looked like 2 weeks ago And here is what it...

Does anyone on here know if I will be able to grow a jack-o-lantern lepto on the same rock as my Mr. Freeze? I spoke to a vendor at a coral show locally that said some of them will grow side by side fibe and some will try to murder each other. Will these two be ok? P

Hi everyone, I observed something like bleaching but I am not sure if it is really a bleaching so your opinions are precious. Any suggestions for what to do in this case will be preciated. So, I have this frag for 2 months perhaps, for last 2 days i observed that it was loosingflesh partially...

All right so here's my story!!! I recently purchased a PC Rainbow Acropora from @WWC and after leaving it in my 29 gallon for 24 hours I dipped it in Revive from 2 little fish and moved it to a recently established 10 gallon quarantine tank. I had used water from my old aquarium and some...

Hi fish people, I got this wwc green birdsnest a few months ago and about a month ago it started bleaching. Maybe six weeks at this point. This is my first coral that's started doing that so I was slow to react. I've lowered the light intensity and the time the lights are on. It's still slowly...

I have been an aquarist of sorts for over 10 years now, but didn't dive into the salt side until just over a year ago. Like most people i started small with a bicube16 and probably didnt do enough research here before starting. Long story short, I started with Coral Pro salt mix and never once...

Hello all, my friend bought me a birds nest acropora two days ago. It doesn’t look too healthy in my opinion so I am concerned my tank isn’t up to snuff, the rest my corals are really healthy and growing just this one isn’t (or maybe I am just overreacting) My tank parameters are as follows...

Hey guys, So my green Slimer is on a frag rack and I noticed that part of the body and first bit of the branch is bleaching or dead? I am not sure. Since this part of the Slimer was in the shadow do you think this was why? Recently I had some pretty heavy temperature dips because of my own...

I am having issue with my acropora corals, the color is fading out, other SPS are doing good with out issue, such as my montis. The acropora has been in the tank about 2 months, seem to be doing good but over the last 3 weeks the color is fading. I have a few things I am working on, first is...

My tanks recovering from a bad time. I lost a lot of SPS to receding skin. My colony of red planet is 90% dead. Now that I’ve corrected the issue, the receding has stopped leaving 10% alive. I had something similar to this happen before and the red planet quickly recovered and grew of the dead...
