Hi bradtvan,
The chlorine vs. bromine question is a complex one, made more so by
the demands put on institutional, as opposed to residential, pools. Of
course, without knowing much more detail about your particular
situation (geographic location, indoors or outdoors, local water
chemistry, etc.), it is not possible to make any recommendations, but
there is a good deal of on-line information available for you.
For many years, chlorine was the de facto choice for pool
purification. It is still the most widely used, by far. However,
beginning in the early 1980's, bromine became a viable option. It is
extremely stable in water, less irritating to the eyes, kills bacteria
and viruses very effectively, and has a high evaporation point.
Unfortunately, bromine is not a perfect solution. It is, among other
disadvantages, reported to be more carcinogenic than chlorine. This
website, although aimed more at spa usage, has some very interesting
general information about the advantages and disadvantages of both
chemical approaches:

In researching your query, I discovered an interesting Australian site
put up by Trevor Kroll Pty Ltd, which is actually a computer software
and programming services company. They have compiled a rather
extensive database of swimming pool information. I'm not entirely sure
I understand their motivation for doing this, but at least they would
seem to have less of an ax to grind than a pool supply company site.
This is their main swimming pool page, with links to a number of pages
within the site containing related information, including good
sanitation term definitions:

You may also wish to go directly to this page on the Kroll site which
has a side-by-side comparison of bromine to chlorine (which comparison
is not complete because it omits some of the downsides of both
chemicals, especially bromine, but is nonetheless a useful tutorial):
http://users.bigpond.net.au/tcroll/technologies/pools/clbrcomp.htm
Here's another interesting side-by-side comparison of the different
pool sanitation methods (since no one source is comprehensive). Again,
this site is oriented toward spas, but it highlights some essential
points such as relative costs of different systems:

Here's a really excellent glossary of swimming pool maintenance terms
put up by Confederate Chemicals Ltd, a UK company which sells pool
chemicals of all kinds:
http://www.poolandspachemicals.co.uk/poolgloss.htm
They also have a page of recommended books:
http://www.poolandspachemicals.co.uk/books.htm
Speaking of books, this one on the Amazon.com UK site should be highly
useful for your needs: "Standards of Swimming Pool Water Quality and
Operation" (warning: it's expensive):
http://www.amazon.co.uk/exec/obidos/ASIN/0900103698/ref=sr_aps_books_1_3/202-3689501-7631859
Although you did not specifically ask about it, you may want to
consider an additional pool water purification method: ozone. This
method is expensive and may or not be applicable in your situation,
but it can be used in combination with either chlorine or bromine and,
in so doing, reduce the amount of those chemicals necessary to keep
your pools' water clean. This webpage, written by Ted Rich at
Clearwater Tech LLC, provides an extensive look at this issue:

No single site referenced above, nor even the combination of all of
them, will serve to educate you to the point of making a completely
informed choice between the two alternatives you asked about. However,
they WILL give you the background and terminology needed to discuss
the question knowledgeably with pool professionals. Once you
understand the pros and cons of both approaches, you will be able to,
when that information is combined with the specifics of your
situation, reach an informed judgment.
