I wouldn't bother with "Saltwater Aquariums for Dummies". I wanted to get a saltwater book last year, when I got into the saltwater side, and I skimmed over this one at a bookstore and it wasn't spectacular. If this is your first "serious" tank (testing, proper cycle, research, time, more money than goldfish), then it's helpful.
If you've kept tanks before, than you'll find a lot of the information redundant. There are parts in there that are helpful in explaining RO
, water parameters such as Cal. Alk
. Copper. Phos. etc, buffers, and a few other more advanced components, but since it's written for beginners, you'll read a lot about the most common topics talked about on this site. Save the $25 for another book or reef supplies.
