tossing in my 2cents..
I'm just as new to this, if not newer, as you are.
I picked up "The New Marine Aquarium" book by Michael S. Paletta. This was a great book for me. I learned a ton. Course it also opened up a bunch more questions for me, and that let me to this web page. I still have questions but I deff have a better understanding on SW
then i did just a few weeks ago.
If you can, pick up the book I mentioned. It wont tell you everything but it may answer, help you out, and give you an idea as to what goodies you may want to consider.
