bleaching

Hello! I have a hard coral that I got from a LFS about 8-10 months ago. I honestly do not remember exactly what this coral is, and would appreciate some help in IDing it. It is also starting to bleach from the inside out it looks like. I have had 0 changes to my tank besides add a couple...

In my latest post I asked about the health of one of my acroporas as it seemed to have been bitten, it is complitely healed and in fact it si growing a new branch. The problem is with two of the acro frags that I recently moved to the final position after a few weeks on the center bottom of the...

Hey all, Got this a acros like 2/3 days ago, and everything was well. but and then after i dipped, the next day it turns like that. This is my first time handling acros so i’m no sure if they are done (dead) or i should just leave them in and see how it goes? and if yes for how long or what...

Sorry for the long post, I just want to give everyone as much info as possible: 3 weeks ago I bought 7 acropora frags, they all seemed healthy and were bought from a local sps guy who is pretty knowledgeable. I dipped them all in coralRX and rinsed them in saltwater before gluing them to the...

My candycrush started fading a little about a month ago, it was happily in the same spot as it was in the first picture, which was taken July 28th, after noticing the “bleaching” I moved him to the more shaded side of the shroom box I had him in. The fading got worse and he detached from his...

I recently purchased a second-hand 260g reef with a few fish, coral and live rock. During the move, the tank developed a leak. The tank is now resealed and curing, but it's been a long process and the fish and coral died within a few days after the move. I spent a whole weekend scrubbing hair...

Hey, Sorry for the frequent posts. Hopefully this will be my last for a while. On Tuesday, I checked my pH and it was 7.8. Not realizing that that was probably okay I panicked and added APT pH buffer. It wasn’t completely dissolved when I added it and the powder irritated everything and all my...

Help! We have a huge setosa that is a real showpiece in our tank. Last night, I noticed a concerningly large section is dying off, and it's happening quickly. (Honestly, it either happened like within a day, or I'm somehow just completely blind considering I sit and just watch our tank every...

I was under the impression that spectral changes occur in the oceans’ reefs as the sun rises, peaks, and sets. I mainly thought this was the case due to the atmospheric shift in color during sunrise and set. After watching a few in-depth BRS videos and reading some older articles from Orphek...

Hello fellow reefers. I am having troubles with my motiporas. They have been in the tank for 3 months now and in the last couple days have started bleaching. Only that I have changed in the last week was lighting. I am using a reefbreader photon v2. I increase the blues and violet channels...

I have 2 Cyphastria corals in my Tank. One is encrusting and the other is Branching. They are sitting at 100 Par with the branching showing these white lines that look like cracks. I am using a AI Blade light the Parameters are all good and all other coral in tank is thriving! Any ideas what is...

I’m having some really weird stn issues going in in my tank. It’s a 10 gallon and has been going good for a couple weeks i’ve been having some really bad tissue loss on some sps and some lps that i have no idea what it is or what to do to treat. 1.025 sg P04 0.00 (hanna phosphate ULR) NO3 8.0...

My favia (i think) has been bleaching. I moved it to lower light to see if that was the issue but it hasn't gotten better. Please help! I've had this coral for years.

Hi everyone, I have a reefer 170 for about 10 months now (dry rocks started cycling 2 months earlier), but one of my problems is trouble with my first Montipora Digitata's. A while ago, I decided to test some easy SPS, but things have been going poorly. I know my tank is quite new and...

Hi Everyone, So I'm a newbie both here and to SW Fish. Aquired a 300ltr tank complete with rock, some fish, inverts and coral. Unlucky for me it has Aiptasia. I've read all the treatments but for one reason or another I don't think they're safe/practical. Is it possible to cut my corals...

Hello, I’ve recently run into an issue in which my coralline algae is bleaching and I’m hoping to better understand why it may be happening. I’ve recently upgraded my lighting to an aquatop marine (days ago) from the “freshwater” aquatop light I had for a few months. I know I’m not having an...

Hey there, I've recently increased my tank pH and kH by using Soda Ash. I've noticed a significant drop in Calcium (from 500ppm to 155ppm). I understand that it's due to precipitation, but I don't fully understand why Strontium has dropped too... Despite being dosed, it went down to 2ppm while...

Hey, So I woke up today and saw that one of my frag looked like this, the rim of the corals are turning white, no where else at all just the rim near the top. Im guessing that its too much light but he's been in the same spot for close to a month now, and polyp extending great and all that...

Hey there - Receieved my bird’s nest coral one week ago. This and other SPS finished acclimating to light after 5 days and I put them higher in tank due to brownish color. Now, others seems fine but bird’s nest seems whiter than others. Should I lower in tank? Pic and parameters screenshot...

I have read a lot about it. Most say cyphastrea does not require strong light, and thus, I added my new cyphastrea to a little crevice where most of the light comes from reflections after a week at the bottom of the tank in a corner. BUT! lately, I have noticed that the parts of the coral...

I got a $5 frag that the seller didn’t specify the colour of. I think it was not doing well in the sellers tank because it came in with algae covered tips. Well in the pictures it was brown and it did come in brown. After a while in my tank its now a lighter colour, don’t think it is dying...

Hi crap picture but may be able to see if you zoom in….. Is this bleaching ? Not sure new to corals. It’s like a dark purple patch
