Brook or ick in hob filter?

[IzaInTheFog]

Hello, I recently set up my first saltwater tank, and I accidentally introduced a parasite in, I'm not quite sure what it is, but it killed one of my ocularis clownfish. I don't have any other fish or invertebrate in the tank, so I figured I could skip the quarantine process, but I just found out that if I add the medicine straight to my tank it would prevent me from getting any coral in the future. I'm currently getting a QT together to treat my remaining clownfish with a more permanent medication (though he has responded well to a freshwater dip + an extra air stone in the tank. He also still has his apatite) but the only issue I have ran into is I don't have a spare filter (I have a HOB). Would it be alright to temporarily move my filter to

the tank being medicated or not? I also have a spare sponge filter but I've never seen one used for a saltwater tank. Also any general advice for my situation would be helpful, I'll add a picture of what my remaining clownfish looked like before the freshwater dip. Thank y'all in advance and sorry for the paragraph, I know it's a lot to read.

Welcome to Reef2Reef!

Sorry about your fish! Maybe one of the R2R #reefmedic team can take a look for you.

Good luck!

That’s really strange looking. Too large to be ich and too much discrete spots to be Brooklynella. Looks like what we call mucus plugs, but those aren’t common to clownfish.

Can you post a clear video? Hosting on YouTube works well if you can’t upload here directly. The way the fish swims can diagnose Brooklynella over ich.

Now that you point it out, he is swimming a little different than before this whole ordeal.

That's fairly normal swimming, not as "mopey" as Brooklynella shows. The white spots here aren't as large as they seemed to me before, but they are still fairly diffuse. That can be a sign of "old ich", where the infection has been going on long enough that the fish begins showing a mucus reaction to the parasite.

So - as far as I can tell, this is Cryptocaryon, ich.
