1. The Big Picture

How do we get from here, goldfish in a bowl …

to here, saltwater fish and corals?


Start with a container and some saltwater

Simply put, you need a container and some saltwater.  Then what?  Your first or next obvious question is, “what do I do next?”. The reef keeping industry will often answer with another not so helpful question “what [animals and plants] do you want to keep”.  But, for most beginners and many intermediate reef keepers, they don’t know yet.

ReefTank123 will help guide you through a system setup and attempt to maximize your options for the wide variety of fish and corals available.  By the way, the next time someone asks you, “what do you want to keep”, tell them “I want to keep them alive”!

Your options will largely be constrained by, no surprise, time and money.  How much do you want to spend, how much do you want to learn, how much time do you have?

Your first step is to review and research the saltwater animal and plant kingdom.  Decide on the variety and number of species you might want to keep.  That will determine the size and complexity of the system you will need.
