Robert,
Thank you so much for a thourough explanation.

This is a great forum and there is so much to learn it is overwhelming. I have been reading for hours.
Ok, so no on the damsels (this was actually recommended to me at the local FS)
I have also realized that I can do a live reef with a 46 gallon tank. (I was also told it was not possible with a 46 gallon, as that would be too small for a reef)
By reef ready you mean having the plumbing (not sure if that is what it's called)? The tank I was looking at did not have that.

The smallest tank I could find reef ready was a 55 gallon and unfortunately it does not fit the space I have. So, with that being said...what would you recommend for filtration for a 46 gallon bow tank? I am now thinking no on the Eheim internal (after reading several posts), but will live rock, and the Aqua C Remora skimmer would be enough?
Also, what would you recommend for powerheads?
I would like to know why you prefer the aragonite over the crushed coral?
Also, how much live rock would you recommend for this size tank?
As far as lighting...any recommendations there? Obviously I haven't considered lighting as much since I was under the impression that I won't be able to have a reef tank just yet, but now I am set on reef.

I know lighting is very important...also, will I need a chiller? I am not sure on that...
Am I missing anything else for the basic set-up? I wanted to educate myself before going out and starting to buy my system, I do apreciate all the advice.
Sorry for asking too many questions and thanks again for the help.
