How long have you been keeping fish, in general? Not to be rude or anything, but I think most people who have experience with fish don't bother with test kits and essentially just get a 'feel' for how to keep their fish happy and alive, without having to use any kind of 'turbo start' gimmick. I you have one tank running, it's pretty simple and straighforward to get another running immediately using only what you already have (and if how to do that needs to be explained to you, well...). Might be an idea to slow things down a bit and ensure that you're not getting in over your heads with all the tanks, ponds, and rays that you're been acquiring lately. There is absolutely NOTHING that makes up for simple EXPERIENCE with fishkeeping; all the books and forums in the world aren't going to make up for first-hand experience and patience.
