I've had FW aquariums for years but never SW and that's what me and my dad are going to try next we have a three foot tank that holds 160 L's.

So my question is everything. We don't know anything about how much salt or how many fish or what fish get along and how often you need to put salt in. Advice would be great thanks

Hi - the fastest way to quickly get up to speed would be to get a good book on saltwater aquarium setups such as
The Conscientious Marine Aquarist
Natural Reef Aquariums
The New Marine Aquarium
Those are all excellent to quickly learn what you need to do.

We also have several articles on saltwater setups: Saltwater Beginner's Guide

Read and research as much as possible before investing a single dime in this hobby. You'll be so much better off.

Ya the articles that are here are a great place to start. They'll give you the basics and then you come back and ask a bunch more questions.

And welcome the SW world. There is a lot to learn but there is also a lot of people that will help you out.
