Looks like brooklynella and/or velvet.  Please visit http://humble.fish and read until your eyes hurt. 

There's little chance of anything surviving of they look anything like that clown. 

Sorry to bring bad news...

They are nitrile o-rings and will likely keep their shape over time.  I've also found that vinegar or other acids tend to puff them up (in diameter), making them not fit right.  The best thing you can do is replace it with a silicone o-ring.

I just dropped some pom pom and ulva (sea lettuce) off at cuttlefish a couple days ago.  If you wait a couple weeks I may have more ulva.  

Dang.  I've been looking for some used 50ml/min ones.

That said, PM sent with some questions.

Are these the 1.1 or 50 ml/min ones?

Yeah, they should be. They are both k-link (USB-C) devices.  Same app, same dongle support, etc.

I had a similar issue with one of my TDS probes.  Pull it out of the john guest fitting and give the contacts a good cleaning with something that won't corrode the metal contacts and give them a quick wipe down.    That fixed it for me.  YMMV.

Yeah, typically velvet/brook will kill within a week or two.  Especially on sensitive fish. That's why I say a couple weeks of observation is sufficient.  If you need to, do the black molly method. That'll tell you right away.

Don't treat for ich if you're just putting it into your tank with ich.  There's literally no point.

If you have a healthy tank with little fish stress, then ich isn't something you usually see visibly, but it's almost definitely there.   Coral dip doesn't do anything.  

I think you'll be good with observational quarantine for a couple weeks.  Just make sure the big nasties aren't there. Ich, in your system, is inevitable.

Have you quarantined any of your other fish?

If the answer is no, then you already have ich in your system.  Anybody that tells you otherwise is uneducated and shouldn't give advice.  In that case I would say observational quarantine only for 2-3 l weeks.  That'll ensure you aren't getting velvet or brook.  Those are super aggressive and will show in a week or so.  

If you HAVE quarantined your entire system (including snails, rocks, corals, etc) and every drop of water entered into your tank is either from a fully medicated fish quarantine or a 76+ day fishless quarantine, then I'd say definitely quarantine as you did the others..

My guess is that it's the first one.

Hey guys, I finally got hit up in text for the fish and I sold it to a PNWMAS regular.  

Sorry I didn't update this sooner.  Rehomed the fish today.

Nothing negative so far.  I'm usually the pensive one as well, but I went for it.  I haven't had anything crazy happen so far. I may even try the system on wifi again.

I don't actually have one of these to spare, but this one worked GREAT for my 2.5gallon tank: https://www.bulkreefsupply.com/dual-sensor-nano-auto-top-off-jbj.html

Sweet little pump and the sensor is easy to clean and seemingly reliable.

Pretty sure this could have been an email or private message.  

Go on...

Uhh ... That wasn't bad language..... 

Fine.  

300 obo.   Make me a [language filter] offer.

I have a little.  My tank is sterile except for a few aiptasia.  You can just have some.  It grows like crazy.  

Price drop to 300. Gotta move this fish.... Wish I didn't have to.

I have a ton of pods in my chaetomorpha, which makes me think that some of the compact Santamonica algae scrubbers would well as "pod hotels."

Do we know that they actually use a plastic habitat without biological material?

I have a turf scrubber and I have yet to see any decent sized pods in there.  I've looked pretty close too, even put some of it in a jar and shined a light in.  It was quite surprising as there are pods almost everywhere else in the tank. 

In chaeto, yeah, lots of pods.

Mine do get some detritus and such in them, but they are after the socks and skimmer.  If you consider the pods eat detritus, that's a good thing.

@Micah

do you use them for population or to shake for feeding?   

I use them as a safe place to breed away from the greedy mouths of my wrasses.

I've printed a bunch of them actually.  They work great!  I keep them in the back of my AIO's and in the sump of my waterbox.

Oops. Try again. This could explain some things.

As I'm 30 days into my 76 days of fallow (velvet), I'm curious what your QT regime is?  I'm pretty sure I wasn't quarantining long enough (only 2 weeks), and I didn't have any therapeutic copper levels in the QT tank either.  I lost half of my fish, but did manage to save the other half.  Once they're back in the display tank and I start adding fish again, my plan is to increase the QT to 30 days and already have copper levels at least 2.0ppm.  What else would you recommend?  TIA!

Let's not flood my sale post with quarantine help. :). Feel free to hit me up in PM or in a thread post and I'll gladly chime in.  There are a couple other good resources on this forum as well.
