Something Spawned

This one was like I dumped a couple cubes of brine shrimp in the water. Little tiny things that looked like feathers but didn't make the water milky if that makes sense.

Ok, that's weird. Take a pic and show us!

Off the top of my head for causes:

-a big change in pH or Alk that caused precipitation of carbonate (did you dose anything?)
- Medusa outbreak (ie. tons of baby jellyfish)
