For LPS that start to recede.If all water prams are good and have been good.Try looking at your tank at night with a flashlight,about 3to4 hours after lights out.Look for amphipods infestation,some are known to eat coral. When edges are damaged they start to feed. Asterina starfish can also damage LPS edges, then the amphpodes start to feed at night.They can wipe out whole colonies in days.What I use to combat them is Interceptor plus.You could also introduce a target mandarin or a wrasse fish to eat them.
Not sure about revive coral dip as a medication.But I have stopped brown jelly from killing of things before,from frogspawn hammers even a couple leathers with peroxide and iodine dips.
Sorry I didn't get to reply earlier, I'm on vacation atm so trying not to check R2R too oftenI have read everything.
I’m dealing with the same issue. My lps are dieing one by one. I think it’s a LPS infection because the heads that are dieing have a whiteish ring around the skeleton that looks like flesh. I take a tooth brush to it and scrape it off in a bucket then do a dip. It seems to be helping my frogspawn. I don’t see brown jelly but I think it looks like an infection. Any ideas?
I lost a torch, 2 hammers, all acans. Now my octo spawn is starting to receed and my brain coral.
This I changed that might be the reason.
Temp changed from 76 to 78
Switched salt from Reef Crystal to Res Sea non pro.
Increased lighting % on my LED but the coral dieing was before that.
Things our tank has in common that might be the issue:
We have RW-8 power heads
We have Marine Pure Block- maybe this is it!
We both use Red Sea salt
We both have a leather. I just got a toadstool leather and it’s super small.
One thing I notice on your torch is you had vermetid snails. You had a TON of those things on it. That means they are in your tank. I have them and hate them. They send out little stingers to collect food and they will big and kill corals. If those are active that might be your issue.
I’m getting T5 with my leds next week and starting slow.
What are you thoughts? @MaccaPopEye
Thanks for linking the video, I'm keen to watch it later when I get a chance as I have always tried to keep ~75-100 PAR on the sand bed for LPS. I honestly think light will more often magnify any symptoms rather than be the cause, but it certainly helps to rule it out! As I will be trying some LPS again next year I'll be re-checking my PAR in the next couple of months.Do you know what your par readings are? I've always had on average about 125 par on the sand. This past week I saw a video and read an article that said acans are best kept between 25 and 50 par. I just moved and had decided to move back to LPS after trying SPS for the last year. Pretty much only have zoa's in the tank right now so I've adjusted my lighting to see how acans respond. Par on the sand bed right now is 75.
After a lot of research, personally I am pretty confident that this is a myth that may be rooted in truth but spiralled out of context before becoming common in the hobby.I'd say phos is too low for LPS. They tend to like the water a little dirtier. I think most people try to keep it in the .1 - .2 range. Have you ever tested the par from your lights?
I tired this and never saw any pods, but I was also wan't quite looking for them. I also am certain that I don't have any asterina. But this is defs a great tip.For LPS that start to recede.If all water prams are good and have been good.Try looking at your tank at night with a flashlight,about 3to4 hours after lights out.Look for amphipods infestation,some are known to eat coral.

Hopefully these are the cause and you can eradicate them! How did you find them if you don't mind me asking?I found flatworms that hinder lps... treating tank now. Thanks for the help
Two separate dips.Fill a container with tank water,add coral. Pour peroxide in slowly a little at a time until you see little bubbles start to form. Let sit a few minutes.Then place coral in separate container with Lugols,I add enough to color water yellowish orange for about 4 minutes.Then in a 5 gallon bucket with tank water I rinse the coral off and return to tank.I usually do this when I'm doing a water change. Old water for dips and rinse.What was the combo solution? Ratio?
I see you found flatworms,they can irritate Euphyllia Coral.Many ways to deal with them.
Sorry I didn't get to reply earlier, I'm on vacation atm so trying not to check R2R too often
I see that further down you found some flat worms that are very likely the cause, I'm glad you found them. What happened to you does sound very similar to what I had happen. I never found any flat worms, but that doesn't mean I didn't have any. In the end I never figured out what happened but I have gone without LPS for quite a while now (just 2 leather corals and some mushrooms) so hopefully if that is what I had they will have died now, in the new year I plan to try a hammer or torch again and see how it goes.
Your post raised a few interesting things so for any other people I'll add my opinions and comments below.
- Such a small temp swing wont be an issue 99% of the time unless it's happening multiple times a day.
- While salt can be something to keep in mind I also don't think it's going to cause things as long as you keep your big 3 elements fairly consistent during the change (and enough people use RS salt that I don't think that it's a likely culprit).
- Light is always a possibility but in my research I found that corals can survive and even thrive in such a wide range of PAR I found it's usually not the cause but more likely something that can make symptoms worse.
- I checked my RW-8s over many times and there was no swelling of magnets or any parts that could be leaking heavy metals into the water.
- Marine pure is known to leach aluminium into the water, it's now a proven fact. But at the same time aluminium is not really that harmful in moderate amounts and Dr. R. HF has published an article on this. My ICP test also showed aluminium present, but at only barely elevated levels, so I am fairly confident to rule that one out.
- I know a few people have mentioned the leathers as a possible issue but I really don't think it's likely, in my old tank (400L) it was never an issue with the exact same corals and I really can't see a small leather releasing so much toxins that it caused such a huge issue in my 750L system (especially when running GAC as well).
The vermetid snails are something that I don't think anyone else has mentioned yet. I didn't know that they could be harmful to coral at all. I have seen some people call them a pest before but only because they get onto pumps and are a pain to clean off, other than that I thought they were just CUC . I had a lot more in my old tank that never caused an issue, but as I didn't realise they could be a problem maybe when I did my tank swap they ran out of food and started stinging to try and find some? This is something I will certainly look into as I have quite a few of them on most of my rocks!

IMO, "LPS love dirty water" does not mean LPS need, or even prefer higher nutrients
Every absolutely stunning LPS tank I have seen actually runs quite low nutrients (SPS levels) and LPS on reefs thrive in NSW that is very low in nutrients.
I think this myth started as LPS like food particles floating in the water - hence "dirty water" and at some stage this got confused with nutrients. But having lots of food floating around does not need to mean high nutrients. Just because LPS can survive in higher nutrients doesn't mean they like or will thrive in them. And the water also does not need to be "dirty" all the time, in the ocean "dirty" water full of food comes and goes with the currents and tides so IMO and from every stunning LPS dominant tank I have seen, simply ensuring you allow your LPS to eat lots of good meaty foods ticks that "dirty water" box.

I have the same issues. SPS looking perfect. Huge Duncans and frogspawn (10"X10") dying
I'm not 100% sure, however I am pretty certain that the cause of all of my woes was (and still is) vermatid snails.Also had some lps losses recently. Read through this and wondering if you ever figured it out.
