Suggestions on husbandry for SPS

[howdy20012002]

Just wondering what books people would recommend for the most indepth information about chemicals, additives, husbandry etc for SPS.
I am looking at trying SPS again and will admit I am totally clueless when it comes to SPS.
as well, where are the best locations to get the necessary chemicals that I will need.
if anyone has any suggestions as to what they do for their SPS it would be greatly appreciated as well.

there are some awesome SPS tanks out their and all I can seem to do with mine is turn it into a nice bright white piece of calcium.

thanks for the info
Neal
