Yep, that's a "dump and run look"
It will clear up in a few days. the way around this in the future is put the sand in first, place a plate in the middle of the tank and "pump" water in using a powerhead. It cuts down on the white out" look. Rest assured, it will clear up.
Just a hint, when you go to change your filter out cause it's probally clogged, take the hob
unit to the sink before you take the filter out. If not it will just dump the "dust" right back into your tank.
