B.O.D. Bottles/Hach kits

Questions:

Could someone tell me how a hach kit and a biological oxygen demand unit
work?  Would they work very well with being able to tell how much oxygen
(or carbon dioxide) algea use?

And .. can anyone recommend a group of fresh water algea that are easy to
work with?

Thanks in advance.
