that's algae! diatoms i believe.
whatever the case, just wash the rings with water taken from the tank.

it's harmless!
It's a type of algae that grows in places with little exposure to light

Does anyone know why diatoms would be black?

Diatoms are a dark brown ... could have a black appearance .. depending on what it's growing on. They are very common in new tanks and or tanks with water that has a high silica content (uses silica to form it's shell ... gives it that brown algae color) usually tap from groundwater. It comes right off with a rinse and is harmless.

i'm thinking its beneficial bacteria. Ceramic rings are there to grow bacteria, thats why they're so porous. Perhaps thats all it is?

Bacteria are pretty much microscopic, so I doubt it's bacterial.

How many gallons per hour is your filter set up for? How large is the area that the rings are kept in? My thinking is that the flow might be low, which could allow it to grow?
Not sure I'm on the right track, but the Fluval canisters use the same ceramic rings and I don't ever remember seeing this problem with them.

Diatoms are totally harmless. My tank was covered with them right after it cycled and they all died off in about a week. You will be fine
