Hi all.
I am currently freaking out. I’ve had this 75g tank for 3 years. All my inhabitants have been great.
Until recently, I noticed my uv (coraline) and protein skimmer weren’t working properly. (Uv had pump issues, skimmer had calcium buildup)
After fixing them, a lot of shtuff went into my tank. I screwed up a pump and skimmer connector that let some brown stuff and a whole bunch of tiny particles return to my water. This was 3 days ago and there are still this dustylike particles in my tank.
Suddenly, I’m noticing all this dusty stuff on my fish. My gramma can’t stop flashing(he usually did it like a few times a month but now it’s constant) and my clowns, wrasse and foxface seem to have this dust and particles on the fins.
Luckily they are all eating like pigs still. But they still are swimming like they have something they can’t shake off.
Please help. Is this just stuff/particles from the skimmer and filter that latched onto them? Or is this velvet aka the end of my tank. Attached are some pictures. The glass I just cleaned but has that dusty crap stick onto it immediately.
