They make kits that test for each of those. There are liquid test kits, which are more accurate, and paper strip kits, which are easier to use. Either kind can be ordered online.

what do you want to know about? testing during cycling your tank? what test readings are good/bad. get a all in one test strip... they will read all you need to know in one, or two test strips.
