Sorry for a late reply, just got my news back. You can use sand from the
beach, but it needs to be prepared. A long and teadios process.

Seawater can be used, but it is not as good as what you can mix up. read

I want to set up a marine tank (I think its about 35 gallon) with 4 or 5
fish and some live rock *maybe* coral. Can I use sand from the beach? This
is of coarse a salt water beach. If I can is rinsing enough or is there a
better way to clean it?

Also the tank I got is used and I need to clean that, is water enough? I
have heard of some people using vinegar too.

I am not new to aquaria but I am new to salt water so thank you for any
advice you might have.
