White fungus/mold looking?

[Calebsanders]

Hey guys, I've had my tank set up for a week and I've noticed this white fungus/mold looking stuff on my glass. I have no fish or live rock in my tank yet, just some decor from my old freshwater tank that I cleaned well.

I'm new to saltwater tanks so bare with me if this is somthing everybody should kno! Haha

I have some live rock and base rock being shipped to my LFS but idk if this white stuff will be harmful to the rock when it comes in or not. Any help would be appreciated!

Its dust from sand...it will go away after you clean it up and filter catches it

Lol seriously? It looks like mold or a fungus in person. Not really dust

Its from your sand....it comes with slime bacteria and sticks to glass and dust from sand makes water cloudy and sticks to glass...you have nothing to worry about

Alright awesome! Thanks!

I had this in my tank for the first week or two as well. It slowly went away as time passed.

Yeah I wiped it all off and it hasn't grown back!
