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.

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?

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...

Another mass bleaching event hit the GBR in 2022. “The surveys confirm a mass bleaching event, with coral bleaching observed at multiple reefs in all...
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...
Hello everyone i am currently having issues with my lighting. I am unable to get a par meter because it is nor available where I'm from unless its over $2000.
Well i have bleached everything i put on the highest part of my aquascape. Montis and a bali slimmer. Well i am tired of buying new...
I recently downgraded my tank and after a few months I've noticed that my red sea lettuce (?) has not colored up since the move. It appears to be slowly growing, but very pale. My dragons' breath algae is doing well and I've had it for less time.
I assume the change may be because of the new...
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...
I’ve had this tank for about 10 months it is a 20 gallon cube tank and recently I went into the world of sps. I’ve noticed that both of them are bleaching and I was wondering what I can do to reverse it?
New here, hello. I'm running a 150 gallon mixed reef with a 55 gallon sump. It's been up for 2 years but just started adding coral about a month ago. Running 36" dsuny leds and 6 t5's. Before I added coral I turned off the t5's and reduced intensity of the leds to 45%.
This is what was added...
Hi all, not new here, but first thread start. I just noticed yesterday something I've dealt with before and so here is what I saw leading up to finding acro eating flatworms, how I identified the issue, and how I have intially dealt with it.
The last few weeks I've noticed some of my acros...

Goodmorning,
I just bought two lps on Sunday, a hammer and a chalice. It did well the it ate a pretty large amount of food on Monday, but on Tuesday i noticed two white spots on edge of the coral. I also noticed a hermit crab next to it but it was scavenging on the dry rocks. I observed it...
