Setting up 20g tank,, New live sand??? used live sand???

[ReefNightmare]

Hi everyone, I m thinking on setting up a 20 g tank, Can I use new live sand with water from my main tank? or Is it better to use used live sand with water from main tank?
What happens if I go with the new live sand?
I don't want to disturb my main tank.
Thanks.

Are they going to be tied into each other?

you can start with new sand with old water from main tank.
Or you can use a cup of old sand to seed new tank.

Or Start all new.
It is your choice. All of them work.

They will be separate from each other, if thats what you meant.

The question was if the 2 tanks will be plumbed together,meaning will the same water be flowing through both tanks.

i would go with new dry sand imo live sand is a waste of money in time the sand will be full of life...
you can speed this up if you take a cup of sand from a up and running tank and spread it on the new sand to seeed it

+1; using used water doesn't really carry enough bacteria to make it worth while. The majority of the desirable bacteria is on the substrate (liverock and livesand).
