I have read a few published books on this topic, but some are old, and others don't give much in the way of information. Surprisely Reef Central doesn't have an easy to digest guide.. Can anyone recommend a resource for me as i get ready to plan more of my livestock? While i know liveaquaria and other commercial sites have some information, i would like a more independent view. I.e. I would like to read more about the requirements of various leathers, hammers, frogspawn, torch, etc.
