Need help with marine salt -setting up a new tank-

[scherzo]

So I'm assuming that you're buying the tank used.

If you have enough money for the live rock you'll be good there.

Are you trying to find a place for the livestock? If so, see if you can get a small tank or bucket, or brand new garbage bin and make enough salt water for that container. Put the livestock in that while you are filling your 175 gallon tank.

Then once the 175 gallon tank is filled and cleared up. Move everything into it.

That's what I have done in the past.
