I wanted to poll some opinions on test kits used by you guys/girls. I have been using test kits now for about 6 years and have developed some ideas which I need your support. Tell me which test kits you use and the ones which give the best (i.e. precise) results. With your help maybe we can help those people that buy test kits, relying on them to be accurate, only to have things go wrong in there tank because of inaccuracy.
