HELP PLEASE!

[emmaaaa]

Hey Guys I have this tank which has been newly cycled. I have had no fish in it but some of the ornaments (rocks, live plants) have come from my old tank. I have this white stuff growing on some of the stuff in my tank and i am concerned it is ich or something like that which means I cant introduce any new fish. Can somebody please help me identify what this is!! Much appreciated)
((I do have white sand in the tank))

Since you just cycled your tank my guess is a Bacteria Bloom which means your not done cycling. Was the water cloudy for awhile?

It’s not ich as there is no host for it to feed off of. It may just be sand particles settling.

Looks like sand to me
