bare bottom tank

so I am rearranging my live rock getting ready for fish in the future and I notice there is a ton of like dust stuff… I mean maybe its not a whole lot but it seems to be a good amount.

my question is can I get rid of this? it does not syphon out. Or do I not want to get rid of it? Maybe I wouldnt notice it as much if I used live sand?

more importantly will this harm anything in the future?

my water readings are steady… no nitrates or ammonia. ph and salt level good. I do not have any corals or plants.

THANKS in advance
