Top 5 Reasons LPS Corals Die

[@OvidiuDanBogat]

Hi. I just stumbled across your channel researching builds, and you, sir, are criminally undersubbed! The amount of information and the quality of the videos is incredible. Thank you!

[@MiXReef75]

The last part about finding what you looking for in a bottle is great advice. The basics will save you in the long run .

[@artrose3921]

I needed this video. My gonis have been struggling lately. Thank you for giving me a check list to go through

[@Palpatines_reef]

Im glad you talked about peppermint shrimp they are carnivorous glad you exposed them for what they truly are!

[@northeastcorals]

If were talking about the shrimp in the video, it's blurry footage but I'd be surprised if that was a Lysmata Wurdemanni (the true peppermint) or a Lysmata Boggessi, which are similar & what usually gets sold in the hobby trade as "Peppermint shrimp". There are many shrimps sold under the name "Peppermint" & they are very difficult to tell apart, which is exacerbated by the fact there is quite a lot of variations between individuals within the same species. Some are behave the same way as a Wurdemanni & some do not. Even amongst Wurdemanni (& Boggessi) there will be some coral eaters just like with cleaner shrimps, bloods etc. I've constantly kept around 25 to 30 "Peps" amongst my various coral tanks for the last 10 years & touch wood I've not had a coral eater as yet although I have had a cleaner that loved to eat Xenia. I'm sure I will get one 1 day but it seems as though they are the exception rather than the rule (with certain species) & considering the amount of work they save me by keeping my tanks Aip free it's a gamble that's well worth it for me anyway ✌

[@formallydehyde]

@@northeastcorals I think they're also much more likely to attack corals and whatever else they can get their claws on if they're extremely hungry. I keep peppermint shrimp (all L. boggessi so far) because I think they're adorable, rather than for Aiptasia control. So they're fed daily, sometimes by hand. The only live animals I've seen them go after are adult brine shrimp, which are there as feeders anyway.

[@ReefDork]

Torches are a pain in the arse!

[@Grumpydadwithtech]

Mine seems to have lost a head in 2 days, no idea why

[@gotju]

Hi Alex, #5 is getting me as we speak. I have a 110 gallon and I have not been able to keep sps coral and have been wracking my brain as to why. Additionally, my alk, calc, mag, ph levels have also been off. Did some tests, went to my LFS who first thing told me is my salinity was reading 39ppt. Hanna was telling me 35. I’m in the middle of doing bigger and several water changes to lower salinity and get back to baseline. Not sure what cause all my issues in the first place but resetting my tank water parameters with big/frequent changes seem to be helping so far. Great video.

[@jonathanstephens7804]

Great video mate. The old classic salinity pen issues. I have 2 pens and within a week, one dipped to 1.020 whilst the other was 1.025

[@RogueAquariums]

A lot of people seem to overlook their salinity which can directly have an impact of the corals health. Well done Alex.

[@alex_smale]

Great vid Alex. I'm going to turn my lights down a bit!

[@willtel]

Thanks for this. It is disheartening how quickly LPS can head south when something is off.

[@BaoNguyen-eh7xh]

Glad you mentioned shrimp, mine ate two of my Scoly and when I found out it was too late :((

[@geoffW1997]

Thanks. Very helpful. My acan has the same issue as yours in sps tank. It doesn’t grow but I have now reduced the light. Hopefully it will grow.

[@encrustingacro]

Fun fact: polyp inflation/tentacle extension correlates to coral health only up to a certain extent. If you look at corals such as Micromussa, Dipsastraea, Cycloseris, etc. in the wild, they are way less fleshy than their captive counterparts. I have shown wild (true) Goniastrea to some reefkeepers and they were surprised at how drawn tight to the skeleton the corals were.

[@northeastcorals]

Interesting stuff 👍

[@jaysrealreefuk]

Amazing videography of your corals. With the top 3 being brilliant advice for all corals. 🙌 Those Goni's look incredible and that amazeballs coral has some serious pop. Love your frag tank reef. Looking forward to the next video 👍.

[@alarsen18]

I just had a year old duncan coral which started with 1 head and had like 10 mini heads all around it die in a matter of a week or two. Just started melting away. All other corals were fine and the only thing I could determine was the cause is that I switched from All for reef to a combination of All for reef and Kalk, but in the transition I had a quick drop from 9 to around 6 Alkalinity. Don't know for sure though. Agree with the shrimp free part. Very annoying that I can't spot feed since that little psycho goes nuts and rips food out of them

[@СергейКовалено-ы8ь]

Please give recommendations on how to keep Goniopora (food, salinity, additives). Are there any special conditions?

[@ReefDork]

Nothing special with parameters and they don't need feeding. Keeping the main parameters at roughly the correct levels all the time is very important so lots of maintenance - dosing, testing and water changes. Dosing manganese helps too, but gonis are a very tricky coral to keep still. Low to medium light and flow.

[@xisotopex]

any idea why my zoas seem to be getting very drab? they seem to be losing color, yet they are growing...

[@kalan91]

Hey, what about flow? I noticed some of my LPS retracted when I put them in a higher flow area and didn't open anymore. It wasn't that strong flow, it didn't blow the flesh off, etc. Just moderate flow that caused polyps to wave a bit more.

[@ReefDork]

LPS can tolerate much more flow than most people think, but they don't like strong flow and really don't like direct flow.

[@artistic_spaz3724]

I am having a hard time keeping cleaner shrimp alive for some reason.. maybe you could do an episode on things like that?

[@jonathanlee97]

I was losing some lps and finally figured out what was wrong. Refractometer calibration solution evaporated cause its a 3yo bottle so the refractometer was totally out of calibration too. I only found out after getting a new bottle of solution after my mag was testing 1600+. Salinity was 40ppt! And it was at this salinity for monthssss. And during this time most new lps i added were not doing good. Now i got it back stable

[@yunghysterik]

Great video and even better goniopora garden

[@xisotopex]

I am getting different results from my refractometer and hanna salinity checker.... not sure which one to trust... however, I zero the refractometer with distilled water, and then check salinity, and it still doesnt jive....

[@ReefDork]

Optical refractometers (especially good ones like the D-D or Red Sea) are more reliable

[@waterbox_box_joe]

I had a salinity spike and my Hanna checker was reading 1.019 but salinity was at 1.36 smh. It’s taking 2-3 weeks for my lps to bounce back.

[@CaptainSlow299]

would you be able to maybe directing me to a video that can help me help my candy cane coral? I have a Duncan that is doing really well but the candy cane isn't happy and idk why.

[@ReefDork]

This one!

[@skykn1ght78]

Great video! Question: Would you consider a salinity swing from 35 to 32 to be too much?

[@ReefDork]

Yes, absolutely - 32 is too low. 34 is ideal, 33 or 35 are acceptable

[@h2oglassbox]

Yes. Salinity. I have 4 ways to measure it because I’m paranoid about it. I check it daily 😂 I’ve crashed my Fluval three times because of screwing up this parameter. Never again if I can help it.

[@danlahrman5395]

Gonna put this checklist in action straight away to hopefully cure my hammer and a goni. Question: Let's say you move a hammer to a lower light area of your tank. How long do you give it without improvement before you start to think it's something else? I've been moving my fading hammer to lower light areas for weeks and it still is not regaining color even though it is extended fairly nicely. If I want to put it under lower light, I'll have to bury it under a rock.

[@ReefDork]

Corals recover slowly so you're talking weeks, not days.

[@ilikeweirdfish7106]

Hmm… I’ve had some LPS loss and maybe it is my peppermints. Usually they eat all my aiptasia and then get eaten by my wrasse but for some reason my wrasse are leaving my latest alone.

They ate everything, including new fish that I would add. And then peep out from behind the rocks and dangle the left over flesh from fish 😢 I couldn’t believe it until I researched and learned about camel shrimp being sold as cleaner shrimp 😳

[@potsmokeris]

Regarding salinity issue: be sure to check whether you are using densimeter or salimeter! Those are two different things. :) Corals started dying and then I've found out my salinity is almost 40 ppt! Turned out I had a densimeter, LOL
