Dust like material in cycling tank?

[Nanoized]

Wondering where this debris is coming from.

Note..
i've spotted bristle worms ...could this be the cause?

See attached.

Thx

looks like detritus to me... or just silt from the crushed coral.

when you finish your cycle, just add a clean-up crew and they'll probably take good care of it.
