probably been asked alot the first thing i did with my api master kit was break a tube
where is the best place to get a replacements as i would like to get 2 more and make a total of 5 so i can do all the tests in one go

and that was between two test kits. I had to by an ammonia replacement cause ran out and didn't need any of the others I got a tube with that so I'm up to three. You might look at ebay or a place that sells chemistry stuff might be able to get a good deal there. If you still in school or know someone who is and if you have a chemistry lab you could see if they have some.
