Sherri,

I'll second the vote for the system from airwaterice.com. I also got the home/reef system. I'd recommend, however that you opt for the 75 or 100 gallon per day membrane, as it takes a while if you're filling water jugs as I do.

That said, the folks there are great to work with, and they have a very good product. Installation instructions are very straightforward, and easy to understand.
