See below video. This has shown up over the last 4-6 weeks. Seems to be inert, but want to make sure. You'll see the fuzziness behind the fish.
What the $#&% is this?!?!

Assume it may be some sort of algae.... I'm trying to ID exactly what it is. I've been in the hobby over 15 years and never had anything like this. I've read it may be MULM?

Lol that was too easy, right? Sorry it's hard for me to see details
It's hard to make out what you're referring to.

The fuzziness on the rocks that you can see moving with the flow. It almost reminds me of like dust on a ceiling fan.

I'm seeing something very similar in my 10 gallon bedroom budget build. It's like a furriness on the rockwork but it's not GHA or turf algae. Most of it can be blown off the rock with a turkey baster but sometimes it requires a toothbrush and a bit of elbow grease. I thought it might be mulm as well, but I assumed the tank was to young to have that level of accumulation already. (The tank is just over a year old.) I'll see if I can get some pictures/videos of mine as well to compare.
